its not about deserve or equality. They should all have some level of involvement and representation. Numerous racial guards and soldiers exist, thats good.
NPC wise this is fine like with Mishka but faction stuff should be there like how the Explorers League is helping the Shieldwall offensive ( i personally loved retrieving the bell wit that AWESOME sentinel commander who kicked loads of ass with me) or how the Night elves were involved in Kasarang on orders of Tyrande. The gnomes in uldum (which went horribly south)
We should definately have more stuff like that. THey're showing greater Faction leader involvement too.
At most the Draenai, worgen, Forsaken, need the most attention. Tauren too.
