World of Warcraft has always been rigid in its multi-faction system that has Horde and Alliance, but it appears that this is changing with the introduction of WOTLK Gold cross-faction play. The popular MMORPG has been in existence since the age of 16 and all through its existence players have been split between blue and red, and it is only now that things are beginning to lean toward an unbreakable truce. The rift between players, based on which group they belong to is a key element of the Warcraft experience from the beginning, as the lore of the game is built upon the battle between two conflicting races.
Players have to make the option of which faction to choose when they make their first character and based on the race they want to play as. There is an Alliance faction, which Alliance includes humans, dwarfs, and night elves, whereas WoW's Horde races include orcs tauren, and even trolls, the names of many peoples. Players have to remain in the faction they play for in complete isolation from enemies unless engaging in PvP combat or passing them through in neutral zones. Guilds are faction-locked and the only method to change factions is to either create a new character or spend real money to change your race.
Some factions' players have had difficulty understanding one another due to an in-game bot has the ability to translate text into a scrambled form to appear as if the opposite player is playing a different language buy WOTLK Classic Gold. This is a great touch from a lore standpoint but players are getting tired of the ceaseless fighting and the polarization of cultures. But, the idea of faction identity has been a major selling point in terms of the interaction between players for so long that it's difficult create a bridge crossing this kind of a gap.
In simple terms, as soon as the change is made with WoW's WOTLK Classic Patch 9.2.5. players are able to decide whether their group-finding tool will include players from the opposing faction too. It is currently working, the manual group finder will show those who want to join the group in any activity chosen and the leader will decide if they want to invite them. By deciding to play cross-faction, it would merely mean that all players within that domain can now look up and submit an application to join the group.
