idk, in real situations the high supply cost and the limited space really work against raw-roach compositions when matched against stalker/marauder and other units with ample range. including marines. i think, the greater the enemy damage potential, the greater role these things play; Stimmed MMM + tanks for example, are utterly devastating to roaches; there's no need to even kite. for teh msost part (and i find it reasonable that its become hard for marines to kite roaches, though marauders can still do it)
... i dont really mind the state of the roach. most of the time, i might have a problem with them if i felt like they encouraged massing too much, but i feel they combine decently well with other stuff, even lings for early pushes. (especially heading out with a roach batch and reinforcing with speedlings)
they are reliable when matched against lower numbers of enemies or when able to flank, to diminish heir disadvantage of shorter range.
Skyze: cool that, but lets keep in mind that Zergs doing such timing attacks are much more committed to dealing real damage than T or P typically are in similar situations, as you seriously need to hold drone production to make the attack happen..
the statment that they need a reparied bunker to hold it, implies that tehy are not anticipating it and not used to the notion of it; dont know how to hold it, but when they learn, they probably will hold it "every time", without big losses compared to the drones that werent made. if there's a problem, i dont see it!
i actually think zergs might end up needing this option in order to balance things out; threaten putting the heat back on opponents that try to exploit the supposed predictability of earlygame Z
