Dude, you so don't get blown up when your blind. Your radar still work! You just swoop or teleport away from the little red dots.
I had an idea this morning, but I'm running out of time so I'll be quick.
Increase solar flares range, nothing huge, maybe double the current range of melee.
But you have to have the person under your cursor for it to work.
It still takes three quarters of your ki, so your opponent (if he's quick and meleeing with you at the time) will still probably swoop through and get you.
I have another thought. How does solar flare effect advanced melee? You have to try and block blind? could be interesting...
