Wishful thinking but...
I'd like to see some more content released for low level players, PvE similar to brawlers guild perhaps, more BG's / arenas... seriously blizz no new bg for wod?
A new ranged / caster class... past 2 new classes have been melee.
Big nerf to brew monks at 29... plz
Zones for low levels where 100s can't get in? Some sort of bracket that prevents lowbie ganking with level capped characters.
A global level for your account that affects all characters rather than raising cap to 110.
New things to spend honor on like toys, low level gear, new mounts etc.
A community of players that treat eachother with respect and love instead of spitefulness and anger... or nah.
