Shadow Cat variant of the highly successful laser vomit builds on the Timber Wolf and Ebon Jaguar. Sporting 2 Large Pulse lasers and an ER Medium with ECM and a TC1, this build is doing some awesome work for me so far. Playing this as a medium range skirmisher seems to be it's sweet spot. Can run on the hotter side if you lay on the alphas. If you are looking for something a bit cooler, here is a spin on that variant with 2x cERML and 1x cLPL with ECM and a TC1.
I was thinking something similar but cooler. Let the pulses do the heavy lifting and get more sustained DPS too.
This is by far my most effective build thus far. I tried several, this one runs coolest for me, although I dropped the TC in favor of a DHS.
The SHC-A left arm gives a flat 2.5% reduction to all laser heat gen, plus 2.5% to the ER-MLas. The prime only provides a cooldown to the MLas. You may want to switch the omnipod.
