After many days of farming this place I think I got the tactic for every trash mob without wiping. Well... sometimes crap happens and I wipe horribly but its happening less often. I use only 2 CCs now even if I can use all 3 of them. First pack of 4, I just CC the closest with hex, and the healer with my mage.

2nd pack with the patroing and the vortex field, I simply hex and sheep the 2 healers with the tank bodypulling when the patrol is on the north part of the force field using my 50% damage reduction (otherwise she gets toast real fast). Thus, 2 healers are sheeped, I put my team inside the vortex field and deal with the 3 mobs that are not CCed, which usualy is the caster mob and 2 melee mobs. The caster mob usualy is aggroing the healer but since she is on the force field you can forget about it. Then take 1 by 1, refreshing the CC on my mage.

Shooting star pack got their damage nerfed I think? and now I simply heal through maybe using power word barrier when its up but not much of an issue. Next pack the same as the previous one. CC the 2 healers and deal with the 3 melees (usualy 3 melees).

The last pack which are inside the forcefield, I put my team on the stairs, and pull with my paladin and hit bubble. The healers could be eighther 1 or 2, but they will stop casting and come to melee range. When they are close enough, I cc the 2 healers and repeat the process.

Note: There were times when I had broke a CC of the healer and when that happens its usually a wipe. Sometimes the stupid shaman type mob thunderstorms sending my tank back to the entrance which is not good at all. But usualy this method resulted 80% of the time a success. Not sure if it was needed to post but wanted to share for those who may have difficulties on the packs. Of course my team is VERY CC heavy so it may not be that usefull for some teams.
