I chose Mechromancer. It is a pretty cool class. When I only knew about the four characters I was thinking of either Commando or Gunserker. When I found out about Deathtrap and Anarchy I knew I had to pick that class. I looked up builds for it and it looks like it is very customizable with the support of shield recharge, DPS of Anarchy, and the shock to remove the shields it sounded pretty sick.
