1,591 M Xavius kills vs. 1,421 H Helya kills. Even though M Xavius was released a while ago, you would expect those 1,591 7/7M guilds to just go in and kill HEROIC Helya Day 1 especially at their gear levels and for there to be at least more H Helya kills than 1,421 given the 6/7M, 5/7M, 4/7M, ... guilds out there. Why is this not the case?
Now you could argue that these guilds have simply disbanded, but with 4,900 H Guarm kills, this indicates that these guilds are active but are simply not doing H Helya. Why not?
