Bringing in a Druid (insert specialization here)

Heya there guys, I'm currently leveling a druid (level 70 as of right now) and wanted to know what is there in demand.
I'm contemplating going either tank, healer or boomy.
Anyway I just wanted to leave a question, as I'm divided, wich is: -"What is the role most wanted right now?"
I understand there will be people saying "play what you like the most", and my answer to that is "I like them all".
Thanks in advance for your time and hopefully see you in game!

Healers are always in demand(as in any game), tank druid is ok but from what i understand pally and DK tank better. As for dps,its a dps and thats totally on you

Can your druid spec fire mage?
