I'm down for the strike, and I say that as someone who leveled all of their healers to 90 via PVP and tribe dailies/weekly challenges so I was never contributing to the queues anyway, lol.

Healers for me were always in this weird spot to play as because either they were too stressful due to wall-to-wall pulls where I could never get us through it (thus forcing the tank to take smaller packs and making me feel like a jerk/moron because it was "my fault"), or they were boring as hell because I was spamming the same two attacks over and over and over and over and... you get the idea. So I really don't know what I could suggest to make them more approachable or appealing for healer mains or those wanting to try the role out.
