I would be glad to see wolfs/fenrirs here. Yes, there are mounts in classic but not only I found most of them ugly, and mounts are not the same as L2 pets. If it's at all possible to bring it here from "normal" L2..... It's not a kinda major improvement but It could be great feature that will make this server different, in the best way, from other servers.
PS Or at least, replace this ugliest dwarf kookaburra mount with skin of fenrir. Would be really awesome.
