Instead, let's take Battle Cloak. It has a 15 second cooldown after you decloak, but then you can use it at any time.
Why not create a version of Battle Cloak that has only a 2-3 second cooldown after decloak? And then we call that "Enhanced Battle CLoak" and put it on the B'rel.
I don't know man, I think that that would just make things harder for B'Rel pilots; my reasoning is that the ship is considerably more flimsy than the standard T5 with the hit-and-run setups you see, and I don't really see that changing with a quick cloak design, I just see continued dependence on the cloak by pilots.
I think that the answer is to grant the ship some sort of bonus while using the cloak, like a partial shield penetration, or +20% torpedo damage if fired while cloaked, or something along those lines and have the trade-off be that the ship is more easily detected after attacking.
