Related to 2v2 I think the real prove is when a german faction team with 600 hours played by each player is owned by a soviet team with under 100 hours each player that are simply abusing the (whatevernewexploitstrategy)craft which is used by low value players to own better ones.
So what the 100 hours experience guy may say to the 600 hours experience guy? Trololol, L2P?!
That actually tells more about the "experience" and anticipation skill of that german 600h team.
I've faced quite a few people who had 10x more games then me, yet quite a few of them could be stomped by my new AT mate(and they were actually) who plays CoH2 for 3 weeks now.
Time is bad indicator of skill, because you can improve to Jesulin level over a month or you can play all the games in the world and still be 20k+ like wiking or that attention seeking german 4v4 hero who recently flames everything that isn't german faction praise.
