Since 200 cost nerf was unpopular, might be better to target the grenade since it can flip fights so hard.

proposed: grenade -1 range -> -0.5 range, blind removed (the blind hardly ever comes up and is hardly ever intentional, but if all your units happen to be blinded they'll run in and you'll lose a big chunk of your army)

This would make other openers not just flat out lose fights to reapers if grenaded (grenade is half the reason prism is a requirement in every game)
