You got everything you need to disable and hunt down ECM.Mechs. ERPPC, TAG, BAP, 3tons of SSRMs. Sayonara AS7-D-DC & CO.! Blagg
Took your build as my base and made this: I know it's basically a totally different mech but I made so few changes I didn't think it was worthy of a new thread. After some drops I'm not convinced it needs 3 tons of ammo. So I dropped one and added 2 JJs. The difference is noteworthy. I like it.
I'm using pretty moch the same build, although I've got max JJ, 366 armor and only 13 DHS so it should run somewhat hotter then your build. What I really like is the versatility of the build; I can snipe with my erppc, brawl/hunt lights with mlas and three streaks, BAP+TAG helps me support teammates with LRMS. I made quite a few creds&XP in my last game from tagging and countering ecm.
I tried both builds and since I prefer builds with 2 or 3 weapon groups max, the ER Laser one worked pretty well for me.
