We just completed the DS9 fleet action and I have to say that the legate hologram generator power is just unfair. It is not interruptible, it spawns 4 guys immediately, and they can use it multiple times (so that there are multiple generators). We were repeatedly faced with 30+ cardassians because they spawned with 2 legates in the group.
The real "fun" came when there were so many plasma grenades active that we could not even spawn in without dying immediately. I think this needs some serious work. It was purely frustrating after awhile and not even close to being fun.
