The players are not the most obvious or likely. It's simply one of many possibilities, and I'm either proving or disproving one of them.
These numbers neither support nor disprove what you are saying. They only speak to two things: average group composition, and winning percentages. Those are all the answers they provide. /fin. If these numbers speak to anything at all, they simply show that both horde and alliance make similar class choices. I'm not saying this supports my argument, really, but it does not really support yours either. It marginally supports the idea that the two playerbases are similar in some ways, but I dont think in any relevant way.
I'm not looking to quantify "alliance sucks" simply because I cant. I *can* quantify other things, though, which is what I'm doing. My next question is whether or not the median character level is different, but without someone on alliance side keeping some stats on what they are seeing it's kind of a pain in the ass to do. I was literally just telling someone in game that I need to get on fiverr and find a pakistani to write an addon that does it...
