Is anyone using any third party addons? I haven't touched any of them yet, but I was wondering if there are any that have started to stand out as useful additions.

JunkIT is amazing.

Anytquest is pretty awesome to help you track quest objectives. Those are the two I would recommend.

I'm running quite a few, been playing around with them, but before I list them I will say this much, I don't think any are needed, for the most part they're quality of living additions, making things easier or less janky.

• Amp Finder; Pretty much clutch, not only does it show you what Amps are world drops and what are purchasable from a vender, but it'll show you where the hell that crafty vender is hiding.
• BijiPlates; Pretty simple mod that helps displays health bars in a better way, just makes it easier to see what's going on with someone's health pool.
• CustomFOV; Self explanatory, this gives you a way to change the FOV in the game.
• JunkIt; Gives you a one button press trash vender button. The first addon I download I couldn't live without it.
• Lockdown; I found this to be the number 1 game changing addon I've snagged. It set's the camera up to be mouse follow instead of hold right click, and makes it so you can bind abilities to mouse button 1 and 2. This effectively made the combat feel way more fluent (as a spellslinger having to jump, dodge and spam our main attack was getting a bit unruly before). Makes the combat feel way more action oriented IMO.
• SCastBar; Just a cast bar replacement, gives you more options on the customization of it (including latency).
• Scrappy; Replaces the salvaging menu to one that shows you everything you have that can be salvaged, instead of having to go through one item at a time.
• TrackMaster; Gives you a nice little trail pointing you to whatever you're targeting.

I would start with Amp Finder, JunkIt and Scrappy if you're looking to make things a bit easier in game and move out from there. Like I said, everything is quality of living additions instead of must-haves.

I use a few. I mostly find them all useful. Some too useful, if that's possible.

• ActionSetProfiles - for easy powerset switching, also easy importing builds from WS-Base.
• AMP Finder - for easy AMP finding. I'm sensing a recurring theme already!
• BetterQuestLog - for easier quest management.
• BijiPlates - for easier something. Easier looking at health bars... yeah, sure.
• CheatSimon - for easy Simple Simon. Got bored of it so fast.
• CurrencyCount - for ease of tracking other currencies (elder tokens, and whatnot)
• DefaultMount - fixed an annoyance of not remembering my favoured mount. So for easy riding... sorry.
• Ern's Speedy Quest - for easy quest accepting. I like using the keyboard.
• GalaxyMeter - for easy, semi-irrelevant, player stat tracking.
• GroupRadar - for easy not getting lost.
• IconLoot - for easy glance-to-see-new-loot.
• Interruptor - for easy understanding of interrupting at appropriate times.
• JunkIt - for easy selling junk.
• LocalTime - for easy to knowing when to sleep.
• ProtoMail - for easy mail management.
• RareTracker - for easy tracking of rare mobs. Integrates with TrackMaster.
• Scrappy - for easy salvaging.
• TheZone - for easy seeing if I have anyone near me.
• TrackMaster - for easy everything! It draws a line to pretty much anything you could need. It's very lazy and easy-mode. I'm Okay with that!
• TrackMaster: Farming - see above.
• TrackMaster: Objective - see above.
• TrackMaster: Subdue - see above.
• ZenRadar - for easy finding things without using the terrible map. Also see above as it integrates with TrackMaster.
