Agree with both of you, but my sugestion was to be a "workaround" or palliative solution because I think for DPS's is frustating waiting and they don't want to wait till patch 2.1 to see more tank/healer classes to be added to make things faster for them, this is something for them just "Wow, we can make this, I have nothing to do this weekend, I'll implement these changes" (I know is not like that :P).

For the fact that lesser people want to play as tank or healer I'd like to suggest classes for healers/tankers that are lesser "gay" than the ones that exists XD, maybe hiring a ocidental to design new classes based on the role model of the ocidentals (this is just a joke, I really think the actual classes are somehow "feminine" but I know this is not the real motive for players to not play as healer/tank, and I don't want to offend anyone - just to be clear).
