Iapetes told me that he was doing Wintergrasp and beating people 2v1. You might think this just means he's skilled. Math says that's exactly the point and proves that ret is OP.
Let's run over some facts.
1) He was facing another ret paladin plus another player.
To elaborate on fact 2: If you have two equal infinities and add a finite value to one, then divide them, you'll get 1. This is because next to infinity, everything else is infinitely small and therefore zero, so adding the finite number has no effect on the ratio.
To put this in terms of player skill, let's imagine a power ratio exists between all competing groups. This is the ratio of the composite of player skill and class power. In cases where one group loses, it is clear that one is higher than the other. But how can 2 be greater than 1? Simple: Make 1 in each group infinite. This will cause the power ratio to go to one; at which point luck, which is innately infinite, to be the deciding factor.
In other words: Ret paladins are overpowered and this explains how ret+player can lose to another ret.
