If you're talking world pvp and bgs, they are great fun. Nothing better than watching ally getting close to the last wall in SOTA and popping out of stealth with 15 treants and 5 starfalls. Simply dot up the vehicles, and everything close to you dies.

As far as arenas, it's fun when you win, but don't expect to climb very high. There are too many classes with immunity (DK antimagic shell, paladin bubble, priest pain suppression/dispersion, rogues cloak, hunters deflection, etc.) that can survive your main burst and the instant you switch out to heal, you'll get pummeled hard. I recently added a root macro to put roots on all the targets right as I come out of stealth and that's helped a little, but it's not going to be a game changer.

Here's my noob team:
