Well... tac and engie BO's do, sci already have enough.
This issue is compounded on the starfleet side without universal slots. I'm finding my ensign and even lieutenant slots, unless they're sci, to be basically useless. The Defiant is a great example of this level of redundancy. What should I pick? Ooh, let's see... my third Beam Overload? Maybe a third Torpedo: High Yield? The completely useless Tactical Team? Ooh, ooh, ooh, I know! I'll get Beam Fire At Will! 'cause... umm... well... just 'cause.
I see quite a lot of people clamouring for universal slots on Federation side. I feel this is unwarranted. For one, it's a KDF thing and should remain so. And for two, the easier fix is to simply expand the selection of powers so that the enforced stations are remotely useful instead of entirely redundant.
