@ highlighted comment. you're doing it wrong, they are the MOST micro heavy race protoss least terran in between. i've been steamrolled by both terran, zerg, and to a lesser extent, other protoss, you just have to re-learn what role and strengths the units have. you used roaches much yet? if not, do it an early game roach/ling (or even pure roach) army will smash any protoss (no tier1 gateway units are good against them), unless they tech for immortals, which means they'd have been vulnerable to lings or something anyway..
