A couple things.
On the Kraken, can you use sticks at the same time, ala Yamatai's SPINE, or is it more like the YF-21 in Macross Plus, where you're using the neural system only?
When it comes to the Prevenger -- I've melded the two threads -- I'd think it needs more atmospheric range. Not much; maybe double. A higher firing rate seems fair too. Now that I see the fighter to which it is attached, I'm OK with it.
I'm curious about its supposed lack of maneuverability, though. Right now it's an immensely hard nut to crack, but it has CDD, which gives it maneuverability plenty good for the atmosphere and in space. Am I missing something?
