Important! Crossfaction affecting alliance communication and grouping

[norbert.pls]

Bug description: Making cross-faction groups has a huge disadvantage to alliance players.

Being grouped with horde players inside instances automatically sets your faction to be horde. This means that while you are in a group with hordes, as an alliance player, you are unable to whisper, invite or interact in any way with other alliance players that are outside the group. Additionally, you can easily interact with horde players regardless their location, be able to write on horde global chat and invite horde players into your group. Because of this, horde guilds are also able to invite alliance players into their guilds.

This issue should be addressed asap because it is a huge inconvenience to be crippled from being able to interact with guildies and the rest of the alliance faction if you are grouped with horde players (which is usually the case, since alliance has a pretty low population).

It makes you like you would do what you do as Horde BUT you are actually still Ali. The best example for that is when you summon a mount that has vendors on it. They'll be unfriendly to you so you can't "use" them(fortunately, they don't attack).
Must mention that probably this bug has something to do with the lost ali filght points in Stormheim.
