I have a seriously cool tanker with SJ - she’s based on fighting game characters and names Ccombo Breaker. It’s so thematically great.
That being said, I like secondaries that just work. I still think SR is the best you can get, but obviously EA is strong.
i have a Rad/ SR, Ice/Bio, and Psi/Rad stalker, all fully maxed out. The bio can survive well but it is the only one that has died (to Psi damage). The/SR is basically god mode; and the Rad HP can move but like 85% health is probably the lowest it’s been... It is negligible. All have soft capped melee.
Most sets are built similar, just depends on 1. The end recovery you want 2. The damage you want from it.
