Pick whatever you enjoy, everything is viable on pve, and the skill cap for you will be so low in the beginning that your class won't matter really

After you learn the game a little bit and get good you can pick a pvp character to start making, but for now, stick with whatever class you enjoy playing

Druid, monk and paladin can all tank / heal / dps

Try those before you decide on a main

druid gives you the most options and I find it to be very fun.
also gives you the added benefit of being able to fill every roll
tank
heal
melee dps
ranged dps
so lots of options if you don't like a particular spec.
myself I have never been a fan of the boomkin spec.. but I have always liked healing and feral.
