He, so the official borderlands talent calculator is updated to include the talent points from General Knoxx, although interestingly it does NOT include the points available from the Underdome. I think that's telling.  This is my build for Roland. You'll notice that i put at least one point in almost every skill because i want to be able to switch class mods on the fly and benefit from all the plus-to-skills. This is pretty much a build for soloing and i favor using fast, multi-bullet smg's over shotguns or assault rifles.
 
Here's mine

 What's Yours?

not to mock your or anything but i think the rocket for the scorpio turret is more useful than the supply drop especially because the class mod that regenerates ammo's works fine.
mine looks more like this  
lilith + fast firing weapons= win

EDITED to include the rhyme and reason of why I went with this build:  
 
This is all off the top of my head and I'm at work right now so can't check things... but I did find a badass Pearlescent Rifle from farming Crawermax this weekend, which does like 368 base damage I think, plus has special text and has 4 other high stats (like 2.0 zoom, accuracy, recoil reduction, etc.). 
 
I also found and am using a really nice Level 55 Support Gunner Mod, full to the brim with 5 stats (+24 Bullet Re-growth, +4/+3 Barrage/Impact, and 2 other things I forgot), as to never run out of ammo. 
 
I ended-up picking this setup over Rifleman, for the time being, because I'm doing tons more damage than my old build anyway, my Scorpio is constantly refreshing super fast, and now I just play on auto-pilot without ever worrying about ammo.  I also just leave a Level 6 Corrosive Damage Artifact on my Scorpio at pretty much all times.  So that's why I went with this as my final build.  I put my 2 Moxxi Points into Barrage (for a total of 3 base points, which I also get more than that from Support Gunner):

I still need to pick up this game, but I always like fiddling with the calculator. Anyone know if this would be a decent Mordecai build? http://www.borderlandsthegame.com/skilltree/mordecai/#11500550550550015005505

@Novyx:

My soldier build is specifically meant to keep my group alive. here.

" @nethanel: yeah. i have the darndest time finding good rifleman mods. I need a better one and higher level glorious havok. "

I gotta ask: How easy is it to respec? 'cause if it's easy, I won't worry myself over this calculator anymore. Aaand I'll probably have to pick up borderlands when I'm picking up BC2 tomorrow.

This is what I suspect I'll do once I get to level 61:
