Need advice about support classes

Thank you for your time reading this

i like playing support classes that can DPS, played hunter, ret paladin and balance druid, now i am at the point where i want to try some other class that can bring utilities to raid groups AND deal damage.
now, i am thinking about deleting my druid for good, considering recent events(or just playing it as resto for rest of the time here)
i don't like playing priests, shamans and rogues.
can any1 suggest some class or build that is nice dps (not top 5) and that is actually useful in raids?

thanks

Warlock? Just make sure you have 32 soul shards when you join a raid. You'll have 2 left by the time 1st boss is pulled.

Why Warlock? Healthstones, summoning stone, raid-wide SP buff if Demonology, pet duty on BPC, and for the last, but not the least, soul stone.

will try it out, thanks
cheers
