it's like a spiral that feeds itself really isnt it? the veterans are disillusioned and dont want to play the role for all the various listed reasons (tick all that apply), more casual players fill the void because 'ah healer in demand ill fill for easy queue' or whatever the reason, they cant keep up with the content that asks for actual skill when playing healer such as a savage, they also quit, SE response pending but will likely be to make it even more casual friendly, those casuals who joined get bored of the role cos it's so bland now, they leave, even FURTHER casual players (the 'ive got netflix on the 2nd monitor kind') fill the void, etc etc

might as well just delete healer as a role and make it so tanks and dps are entirely in charge of their own selfhealing via their own kits, since they can already do a bloody EX roulette without needing us healers, extremes have been cleared without healers, ultimates get solohealed despite being 'the hardest content available', i cant wait for the inevitable news that 'oop criterion savage was cleared without a healer' maybe that'd get SE to think hard about not just 'is the role screwed' but 'WHY is the role screwed, and how can we fix it with more than just a little sticky plaster?'
