After having major issues with certain early bosses in HFC we finally managed to get a breakthrough and reached Archimonde.
Xhul'horac, Tyrant Velhari and Mannoroth seemed strangely easy compared to some of the earlier bosses and all went down within 5 hours.
So we all know what we're going to hit our heads against the next couple of lockouts. But we really need to speed up the pace and be good on farm nights, so we can get some time to practise.
