I am not sure if it's server's bug. Did you try to repair your character from website? Also, try to delete your cache from your wow folder.
Or they can keep rewarding both 2v2 and 3v3 winners but the top 20 players at 3s ladder should take more bonuses, more mounts, transmogs etc...
I support the suggestion as well
Or they just want to try something new because they got bored playing other expansions. Maybe new expansions aren't that good for some players but it's intresting for sure to play something new.

Try all classes and specs and decide what you like more. Also, I believe that it's better to play decently 1-2 classes instead of playing 10 without knowing anything about the class you play xD
