Mhm. With that kind of ranking "the best" guilds wouldn't be on top. Only the ones which have recruited as many players as possible would be on top and large number of players doesnt mean the guild would be pro. And besides. Those most kills pve monsters would dominate this thing.

The ranking based on most 61s is the most reliable way. That war of 100k exp is that kind of horrible campaign which not everyone want or will do.
