In BL1, currently, my main is Lilith, at 69.
Merc COM with SMG Ammo Regen and damage.
Aside from a Mordy at 13, she is my only BL1 character. I got a late start…
In BL2, either ammo eating Gunzerking Sal or left hand and middle skill melee / slag / DPUH / Fire Hide of Terramorphous Krieg with a Seraph relic that boosts melee damage and action skill cool down time.
In TPS, my playstyle used to be elemental lasers / Bulwark / 3DDIE but, has evolved to cryo/explosive with Shock for backup.
My main would be Aurelia (first to solo TPS with and my only 60+ toon), but i have an Explosive / cryo Too Scoops / Fatale / shock laser / Flakker or Fragnum or Jakobs shottie Avalanche shield cryo or voltaic strafing run Oz kit with SWAB/OLT and he is devastating, currently at 54.
Although i really play Aurelia and Clappy much the same way.
Back in my laser days, CS Athena (53 right now) was my main.
