I do enjoy the mirror event but I really think it due a make over..
The mirror portal could actually send all kinds of stuff though it so we didn't have to fight the same ships in the same formations over and over if your doing this to level. Would in the least be great to have different end ship to fight again rather then the Stadi over and over!
Honestly with a few tweeks here this could be really epic!
I agree, it'd be nice to have more variety of enemies to fight. Right now we just have cruisers, fighters, frigates, battleships, and the I.S.S. Stadi at the end. There should be enemy escorts and science vessels as well, and some more possible named dreadnoughts to fight at the end.
They were originally going to use the I.S.S. Enterprise-F for the mission. It could still happen.
