Right... I do fairly well but I seem to struggle vs protoss once they deathball. Even if I have a deathball myself and more unit producing facilities (better macro because I've been harassing) I just can't seem to win a straight up engage if the protoss is on my level of apm and control. I seem to have problem sniping/emping HTs mainly.
Any suggested approach on this? Part of me tells me to never let the protoss reach lategame but that's just not viable.
