I'm a hunter and my IRL buddy rolls a warrior. We're not that good at PVP but we like to mess around in the arena for laughs and maybe some points. Everytime we come up against a hunter/other class, I always remind him that most hunters aren't very good so we should down the hunter first. More often than not, if the hunter feign's my buddy switches targets.
When arenas were based on 1500 ratings with, a 3-7 or 4-6 week as considered a good week. We would take our 1479 rating happily until we start a fresh 1500 team the following Monday night.
