Just saw some bad b8 thread about there not being a raid in HoW. The achievement system disagrees with that. A few weeks ago I ran level 32 PoE with a friend in my clan. One of the only achievements he has yet to get is the complete a raid with only your clan. We beat the final boss and went to the chest room. As soon as the mission complete timer came up he got the achievement. We are going to try to run it flawless and see if it will give him that achievement as well
