We are talking about a cloak, not a weapon. It doesn't change any stats on the ship.
It just gives it more survivability. Same as a bop.
Why wouldn't the federation have access to such tech? Are you forgetting that phasing cloak they were developing in secret?
You are ranting stats that are totally unnecessary to the point of this thread.
A battle cloak wouldn't change the defiants stats in any way.
Alpha strikes would still be the same as they are now.
Maybe you should stop smoking so much coz its affecting your ability to see reason.
