Please explain why ? And what spec to go into and why ? thank you

Druids is a fun class, and you can choose whether you want to heal, dps, or tank. Its all a matter of preference really. But if it was me choosing, i would go feral, it deals out a good amount of damage, which is the funnest part of WoW to me. Feral is also good for PvP.

Now i don't have a lv85 druid but i have played them a lot in pve and pvp so i know quite a bit about them. Druids have the awesome ability to be able to play 4 specs. Tank, Heals, and 2 dps specs. i personally think druid heals are OP(overpowered). For leveling i would go tank because they can take damage and do lots of damage plus you get instant ques for dungeons which means awesome gear =D. If you hate the whole questing thing go heals and que up for dungeons and battlegrounds. If you just wanna have fun be range(boomchicken) or melee(feral). They have tons of options do what u think you would get the most out of.
