Should i be a druid or shaman for a tauren?

Well, I personally liked being a druid. I think druids are some of the best PvP healers out there right now, and they don't make bad tanks either. Boomkins are one of the foremost DPS cles - I say that knowing I am going to get a lot of flak. However, while I do like druids, there are a lot of them out there and when people are looking for raids, they love to pick up resto shamans for that big walking heroism on. I wanted to go PvP healing on my shaman so I picked tauren and I kinda regret it. They are the biggest ugliest things, I am missing like half my screen. Anyway - for pve shaman-ism I would totally go orc/troll for the bonuses (more pve oriented, I feel)
