That's just how it goes. Game comes out players notice something effective. A small number of them figure out how to counter it while the rest scream op. I'm not saying there is no balance issue just that it is no where near what some people are making it out to be. I don't mind which way it goes nerf, removed or if they stayed the same. FD will just balance the game in another way until the process starts again.
No, this is how it goes:
A feature arrives, and either it works well or it doesn't. At least someone (because this is the internet) will think that it is fine and everyone who complain are whining complaining noobscrubs, and at least someone will think that the feature is completely horrible and will ruin everything and everyone and clearly the ones using it are ganking minmaxing exploiters.
After that, hopefully, a discussion takes place where people attack the percieved problem instead of eachother. The people actually working with the game take notes, do their own analysis of the situation, and do what they find necessary. The problem is solved, and the game is (hopefully) improved.
