So leave a massively overpowered weapon to one side?
Well KDF doesn't have 5 fore weapon ships or 5 tac console faction ships unless counting Romulans, this will be a lot more OP on teams with Kumari, Fleet AE and Fleet Defiants.
Maybe the fed ones should be tweaked then? If they could grant a shield resistance proc instead of a heal they would be the exact opposite of KDF elite weapons and could counter its proc, but maybe this would also be op so not sure if its a good idea.
Also one of the problems is shield resists stacking absurdly high and not enough counters to this besides elite disruptors and SNB. Maybe if more resist lowering abilites were avialable this wouldn't be so much of an issue. Tachyon beam should be made useful and lower shield resists.
