With the upcoming Emergency Conn doff from CE, I feel DHC Battle Cruisers, especially Avenger and Mogh, with DHC will shine even more. I've taken the opportunity to rebuild my Avenger, going all Dual Heavy Cannons up front. Outcome was quite astonishing, melting through enemy's hull with a properly buffed DEM3. Someone probably saw this already in Ker'rat and C&H recently (Deok I'm looking at you lol), but I wanted to bring it up to the forums to get some feedback about it.
There's no RSP, and not even needed actually. the two BFI doffs have 50% each to heal shields as strong as EPTS3 does when receiving damage, 55k hull, 35,8% resist to all kind of energy damage. EPTS3 massively reduces damage to shields, and ET1 keeps the hull healthy. I think hardening shields is better than relying on a single "oh crap!" button. Two TT1 because one, even with AtB, doesn't cool down as fast as two copies do, unless you keep matching their activations every 15 seconds.
Moving with a 35 turn rate with EPTE1, 19,7% CrtH, 92,8% CrtD as attack stats.
