If you're going to do something like that, lower the amount of armor and magic resist given and reduce the heal hugely. It's already hard enough to kill a Master Yi in Meditation, and only hard CC can stop this spell. Making him immune to CC during Meditate means you should nerf Meditate's other stats heavily.
