Exceptional post!
I have played most ATs, but Scrappers and Brutes are my AT's of choice. I started durring beta with a Blaster (rerolled for live) who STILL hasn't made 50, but I have 2 Scrappers who have made the trip and a Brute who is almost there.
Of my 2 L50 Scrappers one (DM/Regen/dark) is Wild (grudgeingly Feral at times), the other(Claws/Regen) is Domesticated (teammates may argue this point... I <3 Scrapperlock! and firmly believe minions die on accident while I am killing off Boss-types), and the Brute (Energy/Energy) is Wild with Domesticated tendiencies, I can & do solo almost anything, but yah gotta <3 the spawn sizes you can only get with a team (and the continously full Fury you can only get with large ferquent spawns)
Now if you'll excuse me I see a group of +4 Dev Earth...
