Here's a list for me, after playing some BF2 last night for almost 3 hours. 
 
Commander 

• Lock Jets and Helis out if some users are being dicks and just wait for it, and then crash it because they suck.  Or they can just have a special Pilot Kit so only people with those kits can use them.  I don't care if people bitch and moan about not being able to fly, guess what...some people shouldn't be flying.
• Let Commander Scoring be stricter.  I know it does a good job with it already, but to prevent new guys from screwing up...let the team vote if the Commander did a good job or not.  If he didn't, he gets no points.
• Add In Tactical Nukes - It's About Time

• If they aren't giving commands, switch it to another user.  
• At the end of a match, the squad votes if the guy did a good job...if he didn't he gets half the points.

I agree with almost all, except for one....

"Hell fucking no. "

I think they just need to continue even more down the path of rewarding following orders. Increase the point bonuses, maybe add multipliers for consistently following orders, points for giving rides and decrease the points given for kills. Or even better, only factor in objective points (descending, capturing, etc) towards experience/unlocks. Also (fever dream), remove any traces of k/d. 
 
The system in place is fine, imo. It's getting people to follow it is what needs to change. Locking out vehicles for certain players is a good idea, but they need to offer some offline practice range in that case (maybe lock people out if they haven't done "training" AA style?)

Aw come on!  It'd be like World in Conflict!  Except without it being a RTS, it'd be the real deal in a FPS! "

 I'm just gonna counter your points instead of coming up with my own. I think they're fine as they are for the most part, but it's been a while since I played BF2, so I'd need to play a lot of rounds again to get an idea of what needs improving or added to the system.

• People shouldn't be locked out of flying helicopters or jets by the commander. What's to stop him banning a perfectly good pilot just to be a jerk, or to help his buddies get in one instead of you? There should be an out-of-server test that you have to complete before you're allowed to fly one, if anything. 
•  Letting the team vote a commander out of his earned points means leaving the game open to a lot of grief-abuse. Commanders in general have to manage their resources and attention carefully - they can't do everything everyone wants them to do. If a player requests a supply drop but is denied by the commander because his strategy dictates that supply drop would be better served elsewhere, that player will possibly hold onto some petty grudge against the commander and vote him down come the end of the match. A majority mutiny during the match is the fairest way to deal with a bad commander. 
•  The game doesn't need to go nuclear in my opinion, I'm quite happy with bullets and grenades.

• How would that work for a group of clan-mates in a squad, conversing via microphones, who don't need to use in game commands? In general, if you join a squad and the leader isn't giving commands, you can just leave the squad and join another or create your own. I don't think there's a fundamental flaw with how squads are currently set up. 
•  Same thing with voting down commanders, it's open to too much abuse in my opinion.

I disagree with every thing you said.

Lock Jets and Helis out if some users are being dicks and just wait for it, and then crash it because they suck.  Or they can just have a special Pilot Kit so only people with those kits can use them.  I don't care if people bitch and moan about not being able to fly, guess what...some people shouldn't be flying.

 Squad Leaders 

• If they aren't giving commands, switch it to another user.  
• At the end of a match, the squad votes if the guy did a good job...if he didn't he gets half the points.

There needs to be more incentive to do what the commander says, or even penalty for not doing what the commander says. There are a handful of dbags in every game that want to turn every mode into deathmatch and there needs to be more in the game to keep that from happening.

Also there should be some kind of democratic way to replace a commander who makes "bad" decisions. I have no idea how that would even work. On PC you could have a hotkey that challenges the current leadership and if over 50% of the team agree (by hitting the same hotkey), the challenger becomes the new commander. It wouldn't require everyone to vote, if 16 people on a team of 30 vote for it, it happens right then.

I think the Commander Role should be changed into a God perspective instead of having it be a person. There's not a single commander that throws himself on his stomach behind the closest wall and throws up a tactical map.
It worked fin in 2142 when your commander could hide in the Titan but that's about it. You should be able to take out the Commander's armaments, not the commander himself. 
 
But overall I think the Commander role worked for what it was in BF2, you just need a lot more rewards for giving orders that get followed and for the soldiers to follow the given orders. Team players should advance faster because they get more points from doing what the commander orders and not just run about on their own.  Also it need to factor in more than highest rank when deciding who of multiple people should be the commander. If two commanders have the different ranks but one has more team kills or less commander xp per played commander hour then he's clearly not suited to be the commander.
 
The system worked. It just need the xp system reworked to motivate the team work.  Maybe special unlocks during the match if the team performs well. Like kill streaks but..  

team streaks!

It sounds like you just had a bad match and are raging.

I completely forgot about Battlefield 2. Yeah the problem with being a commander in BF2 is there's no real value in being that guy. So people don't care either way, commander sets a goal and dudes just go "nah I'm gonna camp or wait for a vehicle respawn". Again, I don't know how you make them really matter without changing the game in fundamental ways that people wouldn't want. They should just have a new game mode and experiment like crazy.

Unless you're in a clan or with friends, Commander mode in BF2/2142 is an exercise in shouting into a void. You get points for staying the commander, spotting people, marking objectives and dropping a UAV/artillery strike every so often. But most people on public servers don't give a shit about your help, and in one server I was even mutinied without explanation. It wasn't like I was leading anyone directly into ambushes. People just want to level up by themselves.

Also, no fucking nukes in this game. Don't give them any ideas. And while I agree with the other points in theory, I am afraid in practice it will cause everyone to curse the mothers of all commanders/leaders.
