Oh....my....agawd. You guys had me excited about the AI and galactic conquest overhaul, but this? This is just... I can't even elaborate on the magnitude of my excitement! Can't wait, you guys kick @$#!
Honestly, I think the main balance issue with the Sovereign is not its cooldown, but the fact that it can fire in any direction. I'm not a super canon buff or anything, but firing the super laser backwards to hit a ship seems unlikely, you should have to have a proper firing arc.
