I think you need to be a little more careful with your bio-ball in pvt, but I do agree with you that protoss is insanely good haha.
Blanket EMP alone wont get you wins against their 1a, you need to split and back up, avoid storms + coloss, etc. Bascially requires much more skill than the toss
you ate a lot of aoe in the games i saw, and I feel your pain because I switched to terran a while back and i know what that feels like after dishing it out for so long :D. I think you're like 1 step away from crushing most of these toss, and I think the problem lies in how you're positioning your bio!
