Or maybe, just maybe people can stop playing the easier roles and actually have a desire to take up some responsibility. Adding bigger rewards are band-aid fixes. Quite frankly, it's a society problem than a game problem, people want to be lazy and take the path of least resistance. Look at all the Don't tell me how to play/I play how I want threads, people crying about simplistic rewards at fanfest, and all the unnecessary nerf cry threads, a clear form of self entitled mentality. That excuse of "it's just a game" is a heavily abused line. It's a line I see most lazy people use when they refuse to watch a video for EX and T5+ and/or any form of real criticism (hence the I play how I want mentality).

TLDR more people play tanks and healers without extra rewards. Take the more difficult path for once and as a whole queue times will drop.
