Just couple days ago I went to LFR that killed Garrosh Hellscream with an extraordinary tactic.
One of the healers claimed that we should keep stacked in one spot all of the time. We cleaved and aoe healed untill boss died (of course did middle phases normally). No movement to anywhere at all (except the iron star guy).
Have you guys encountered this kind of tactic? I found it a bit game breaking (taking away all the excitement).
