Well, I don't really think that's the problem since you can already beat healers 1v1 right now due how imbalanced everything is.
Currently every dps spec has a number of specific offensive cooldowns and defensive cooldowns. Right now, the specs with the greates amount of those cooldowns wins 1v1, in our case that are beastmastery hunters and warriors.
EDIT: What I mean is that currently classes with the highest burst yet good defensive abilities win and rest dies.
