SHARING - PVE - MM - Bot/Dark - Mids' Build Included
Wow, GM killer huh? Very impressive!
I'd just like to chime in that Bots/Dark doesn't "need" crazy slotting to be fairly powerful in PvE. I don't mean AVs and GMs, but regular content, even with the difficulty turned up. Bots are very survivable, can't be mezzed, and Dark Miasma is just an extremely potent set. The -ToHit, mez, and excellent heal, plus Fluffy (who adds more of all three), plus the Tier 2 bots' ability to heal the other bots.. very solid.
Here's my Bots/Storm's build, all Generic IOs and she still holds her own very well in most content.
