Why do people need so-called "incentives" to queue arenas or rbgs? Most people I play with don't play for pets or mounts. Most of us play either for rating or to win, which kind of go hand in hand. I don't see why people need incentives to PVP. If you want a pet for 100 arena wins - why do you need *that* pet? If pets are that important to you, why dont you pet battle with other "rare" ones (because by the time you get it, it won't even be rare)?
Can't people queue to have fun (which is nearly impossible with this balance so I don't really blame you for not)? Can't people queue to just win and be satisfied by the fact that you won? Why do you need something in addition to your win?
