What does the Horde need?

Hello everyone, Krellian here!

You see, i play at the Alliance and decided to change pace and roll Horde and know more about the 'other side' lol.

But being honest: I would like to know more about what roles, PVE oriented, we lack on the Horde (DPS/TANK/HEAL). And inside each one: is there a lack of a class, or a higher demand of them?

Thanks, in advance, for all replies.

The least played classes are allways Warlock / Shaman / Druid, Recently I seen a massive drop in the ammount of Hunters and Priests aswell in pug raids for some reason but that changes from time to time to something else and allways has been.
The most important question is what you enjoy playing, and just go with that.

least played classes are warlocks becuase they are forced to go demo, shamans becuase the are forced to go resto without any chance to play other roles in the 99% of the cases and hunters becuse they have to do a lot of mechanics, also holy palas are in demand but in the end all holy palas swap to retry and pew pew
