Time of day would be the BIG thing to work out.. WT had trouble doing it late evening server time and the 2 times I personally tried to resurrect the HoW only one guild was interested. As for location we found the one Faction base Trials maps(Trial of Towers map 3) worked well, since if you died you get tp'ed out. Seeing as theres 3 islands in the one map there could be quite a few things to work with
