yes i do. 5 banelings kill one marauder, so if i have the counter to his army, hydra bane or roach bane, i need to kill off the marines he has. but if he puts 1 or 2 marauders in front, i will kill 3-4 marines or nothing. they are armored, but i think they should die from one baneling less. and i have seen them in plenty of games, only hard counters really counter marauders, which are tier 1.5. Its the same with marines, only hard counter counters mass marine good and they are only tier 1. But they are not so op(the marines).
And FFS THORS ARE FUCKING OP. 5 broods vs 5 thors and WTF thors win, they just need concentrate fire? My hydra army will be decimated by thors. 3 Thors and 2 siege kill off my roaches. Thors are Sooo cost effective that its op. Muta will die to thor marine. If the terran player doesn't sux, and has 3 thors, with just a few direct counters to my units, even if my amry value is higher, i have no chance. And have you ever seen mass thor in team games? They can kill the ultralisk as if a marine is shooting a dog. Their ability can be used to kill immortals and colosis. And it takes ages for zergings to kill the thors as the thors have 400 life(which is also part of the reason broods die to thors). Roaches do counter then really good, but as i said while the roaches kill the thors a few tanks can kill of my army.
Ultralisks sux so bad againts terran. They should be able to kill off his bio army, as they have splash, so it looks like they are supposed to win. But mass marine can actually kill a few ultras before they get to the marines. if its on a choke, ultras are useless. They need the health nerf removed.
