My hunters aren't quite 60 yet, as I'm messing around off and on with 3 other sub-60 teams at the same time.
They are very fun to play and absolutely destroy PvE content, which is good as I wanted a team which would be able to do a lot of dailies in a short amount of time.

Pre-BC, my solo-hunter (now part of a 5x boxing team) was exceptional in battlegrounds.
That never really translated to arena for me, but you never know when you'll find the winning combination.
A lot of teams can be successful with 4x one thing and 1x another, so you might be close to the winning composition with a minor change.

As Lance said above me, as long as it is fun, that's what counts.
