World of Warcraft has a few significant updates for the PvP population of the game as well as a myriad of other improvements.
Patch 5.4.7 marks the end of season 14 for PvP and the beginning of season 15. PvPers will also see a buff to level 90 players' resiliance and some terrain and NPC changes to the Alterac Valley battleground. Other additions with the patch include an upgrade of Timeless Isle weapons to a higher item level, an improvement to Honor gear, and a few tweaks to Warriors and Druids.
Our sister site WoW Insider is speculating that following patch 5.4.7, Blizzard will start putting out pre-orders for Warlords of Draenor and offering the option to purchase a level 90 character in the store.
