zerg is fucking awful
clearly weakest, least reliable options early game. any viable pressure is nearly a complete allin, besides light roach aggression which is easily nullified. both t and p have lots of ways to put game ending pressure on z early and half of them arent even close to allin, and most are unscoutable and have different counters.
and the idea that z is somehow the strongest late game race is fuckin absurd. hive units are nearly useless and horribly cost inefficient unless broodlords catch them off guard. ya, you can insta remax if you're allowed to get a giant econ, but remaxing on lair units vs collosus or tank based armies hardly matters when you can trade 200/200 for a tenth of their army.
if z guesses, and guessing is required if t and p dont show a ridiculously early expansion, correctly and hits drone timings perfectly then they have a mid game advantage, but its not an advantage that can be used very well. its very easy for t or p to make themselves unkillable and head for that invincible late game army. z gets to use their unit advantage to tech towards hive, which can be nullified, or to expand a bunch so they can throw away a few extra 200/200 armies before getting rolled.
zerg is failing massively in just about every statistic besides gsl first places. the race is fucking awful. i honestly have no idea how so many people dont acknowledge it yet. zergs performance in the foreign scene is very nearly non existent. i think morrow has won one viking cup and otherwise 0 z wins since i won mlg dc. and a pitiful number of titles before that.
