As more expansions are released and the addition of new classes and races, Blizzard will no doubt make some additions again like in Cataclysm, so which new class combos would you like to see?
Obviously some people will not like some over others either from lore or game dynamics standpoints, but i have thought about some possible and feasible additions and this is purely for fanboy theory crafting about what YOU'D like to see.
personally for me Dwarfs and Trolls are perfect and spot on.
Horde:
Undead Paladins
Orc Priests
Blood Elf Shamans
Alliance:
Human Shamans
Night Elf Paladins and Shamans
Gnome Shaman's, Paladins and Hunters
Draenei Warlocks
