The problem is even though mech isn't as mobile as bionic it doesn't matter, because they're so powerful they're guaranteed to win in a base race. You can't just run around a mech ball and win, as a Z player losing an expansion also means losing production, it hurts twice as much compared to the other races.
And roaches aren't really much faster than thors/tanks, not until creep is spread all over the map, which takes me a lot longer than the amount of time it takes T to mass up a mech ball and push. They move even slower when burrowed.
I've yet to try brood lords simply cause their tech pattern is so damn long, and most of my games are over before that would even be possible. It'd be nice if there was a use for corruptors against T so I could at least do something with them while transitioning to brood lords. They do seem like the best counter to a ground based mech build, but lasting long enough to actually reach hive tech is easier said than done. What league are you guys in anyways, do you have any ZvT replays?
