I go one thing, they tech switch before I get a chance to attack with it. Every time I play against zerg, and sometimes protoss, I feel like someone is just creeping on me because of the scouting units they have. I know how to kill them I'm not stupid lol. Just the thought of them there is like grrrrrr.
I just traded really well against a giant number of infestors and then 2 minutes later he has like 50 roaches and a handful of mutas, which means my tanks are like ohhh nooooo.. and they're gone.
I'm just a little frustrated because against protoss, at my level, as long as they don't go mass collossi, which I'm terrible at engaging, I can usually win the game. I guess you can say I'm scared of zerg haha, yet they make up so much of the ladder.
Oh well.. I enjoy hellions so that is a plus :p
