As the title say, depending on the role and the ability pruning/new rotations we know so far, rank the classes/specs from the easiest to more complex to play. Try to be subjective and keep out the drama for your lovely class/spec
Example:
Tanks
- class 1
- class 2
- ...
DPS
- spec 1
- spec 2
- spec 3
HEAL
- spec 1
- spec 2
- spec 3
