New To Raids
Step 1: Ditch the Dragonhunter.
It’s not that they are necessarily bad but there are very few people who will take an unproven Dragonhunter. They are basically the lowest tier right now as far as raids are concerned.
It’s possible the next balance patch will solve some of this but we’ll have to see.
If you plan on pug raiding you will have a hard time getting a raid group as a Dragonhunter at this point. Joining a guild that does raids is really the best solution as you will have teammates who will be patient with you and raid with you to teach mechanics rather than go for a kill immediately. Even if you had a “meta” class you would have a hard time finding a pug group that would be patient with you as you learned the mechanics of the fight, since for most people the times of spending hours grinding a boss while players learn the fight are over; instead people just want to complete the raid as fast as possible. This is even worse for you because on Dragonhunter your only role in the first raid fight (VG) is tank, which is extremely difficult compared to every other role in that fight.

This.
Also for guilds there’s plenty on the forums here in the “looking for” section.
