Don't pay any mind to the whiners. They just can't accept the fact that they lack the skill to counter a simple strategy.
I've been complained to so many times for being a sneaky player and surprising the enemy out of nowhere, despite not playing stealth characters, it's genuinely lead me to believe that people can and WILL wine the moment something doesn't go as they would expect.
One of my best examples being a game where the battles were tight, no one could push, then someone on our side slipped (Can't remember if it was me, probably, but w/e). From that point on they were nailing us pretty badly till we decided to adopt guerila tactics and turned the game around, allowing us to make a comeback victory despite the level/kill difference.
They carried on calling BG and saying we were noobs and such, but the fact remained that they were completely unable to stop us the moment we stopped simply going head first into the slaughter house.
I mean, if not that, what WERE we supposed to do? Let them win just because they had a level advantage and better team battle makeup? Were we just supposted to yield to all their AoEs and stuns that was proven to not be aproacheable by our entire team?
