he just plays coh2 like it's starcraft
Well it surely works, look at this guy's stats.
I can't understand some of you guys. If game allows something then is legit untill it is changed. Truck pushing was legit, now it isn't anymore, as simple as that. Revert these changes? No, for sure, Relic won't bring this back.
Also blobbing: does the game allows you to do this and you are often rewarded for playing like this? Then blobs FTW untill Relic changes the meta. The chivalry is daed since Middle Age, every player does what he can in order to win. Some have better micro and skills and like to use combined arms. Others have not such good skills or are to lazy and prefer blobbing.
You will say PTRS blob it's also legit because game allows it, and of course it is, though it appeared due to a RELIC conception mistake, that we are trying to change right now. Like truck pushing in the past.
The only thing which is not okay is using cheats (like maphack) and that should be severly punished. Like ban on product key, that is what I would do. But that's another thing.
