And what percentage of it? Here is where we touch the probem. If such a player is automatched with a 24/7 coh player but with lower stats (because smurf account) he will be smashed. This is where it becomes unfair.
Doesn't make sense. If you don't play enough to progress, facing smurf or not, you are going to lose vs people playing more regularly and improving their skill.
Nothing really unfair here.
