well, batz is batz. the thing about batz is, he really likes to overexaggerate and not many like that. but atleast he invests into researching his statistics. so yes, batz is like the prototype of every zerg-defender, but if you compare him to f.e. a playa, which would be the prototype for a toss-whiner, he dont whine like an idiot. if he claims something, he has almost always some kind of statistic.
that 2nd guy is a toss player (atleast the profile says so, i dont know who that is), so you cant count him on the zerg side.
and the 3rd one, mystikast… didnt whine about how another race would be op. he claimed, that mutas are too bad for their cost (which is actually true, but anyway, dont wanna open that topic).
its a difference, if you whine about another race being op, or whine about your own units are trash. like, if you look at the current whine wall, its all about “zerg being op” not something like “meh, cyclones are trash” thats a difference.
so, you named batz, a toss player and someone who complains about his own race.
on the other hand, you can easily find 10000000000 threads about zerg being op in the past few weeks.
