It's a harasser build: DPS is technically shit, it's difficult to get high damage numbers with, but damned if this build doesn't generate aggro like a boss. Nab all the cooldown nodes in the skill tree and you have 8 damage almost every 2 seconds with nice range to match. Since it's a zombie build with dual MPLs twist around and sacrifice everything else as you take damage.
Are you sure this is a Krev build? Is it even possible to overheat? If you shave some armor, you could swap those MPLs for an ERLL and really get to some long range annoyance
Amusing that it becomes even more impossible to overheat by going with the ERLL. Logic in the MPLs was to give as much damage potential as possible while in zombie mode. Also because I just didn't know what to do with this mech. AC10 is a straight swap, which works pretty well but at some point I apparently decided I needed range and velocity more.
