Title says it all
Do you think there will be a time where little horde and alliance children will go to raid together!?
I predict that if we do end up having another burning legion xpac the time will finally come where we will actually work together in game. Maybe the decision to give org back to the horde after the alliance cleans there mess will pave the way to better relations among horde and alliance. Both sides have had losses and triumphs but to take on sargeras will need to work together unlike ever before. This wouldn't mean an all out end to the war between horde and alliance but it could bring a whole new refreshed dynamic to the game.
Could you imagine raiding with more races. Some games already use this sort of dynamic in there games that's why I think this is highly probable.
