Cross-Faction

Turtle-WoW implements cross-faction features, allowing horde and alliance to join parties together, do dungeons and raids, mail, trade in a party, and every Auction House in the game is also merged into one, so horde and alliance can easily trade for a single server economy.

NPC reputations are still in place, so alliance players are still permanently hated by horde NPCs and vice versa, so while xfaction party summoning does does open up alliance RFC and horde Stockades, the guards might cause trouble. Because many quests still remain faction exclusive, there are plenty of quest and reputation reward items that remain exclusive for their faction. The NPC rep issues also mean that players wishing to play together xfaction, will have a good time mob grinding, but as for xfaction questing, they will be mostly restricted to neutral faction quests (which are sharable xfaction), and the few later leveling quests that have both horde and alliance versions for the same quest objectives.

PVP is also not cross faction; battlegrounds remain horde vs alliance. As for world PVP in xfaction parties, PVP within them is fine, however faction A healing and assisting a faction B player is prohibited by the server rules.

In PVE group dungeoning and raiding, Paladins' and Shamans' totems blessings and auras now all stack with eachother—however, Magic Resist auras do not stack with eachother nor Mark of the Wild, only the strongest will take effect.
