Arena just depends on what you want out of it.
You want rating, e-peen, the best gear fast - roll a FotM class and cheese your way to 2.2k There is VERY RARELY a season in which some completely derp combination can't get to 2.2k rating using a simple formula which blizzard haven't tempered to be in more in line with what other classes can bring. I'm not saying you'll get there without a few losses to people who actually know how to play. But yeah any hunter who wanted to hit 2.2k this season and didn't is a massive failure of a competent player
You want fun - play with your mates and give 0 shits about your rating.
