I only picked the classes that have problems in arena and usually don't get very high.
I'm going for balance druid because I play it and I can tell you that it is freaking hard to get a good rating with.
Do blizzard ever read or care about these threads? Balance druids have been shit for 5 years straight.
ps. please be honest lol don't pick something just cuz you play it! :P I really do think balance druids are the worst.
edit: I added 2 more options and hopefully it will balance out a little bit.
