Gruuls and Magtheridon's lair

I was fortunate to be involved in a guild run of the 2 bosses today. Got a feel of what it is like in a 25man party. I think because the tanks and healers were relatively geared, it wasnt too hard when everyone listens to their respective tasks dished out by the raid leader. Me, as a first timer, just go there and dps haha. We did wiped once at Mag's lair because the tanks wasnt getting heals from wat i heard over the vent. Although i never gotten any of the loots, it was a fun experience after all!
