WoW torrent

hi little question on staff:
i found on download page of warmane there are today 2 new torrents - Mists of Pandaria and Mists of Pandaria (old) but both are on patch 5.4.2 why?

One is with WoD character models, and the (old) is... well the old one :D

Mist of Pandaria = MoP with Wod model, stay away from that too often generates Error/crash
Mist of Pandaria old = the standard MoP
Both are 5.4.2

oh and i hope that patch 5.4.8 already out :D
