Except you fail to realize somehow even now that while dungeons are done often, they are general roulette content, content we just do without much issues. Want one of those? Go do Criterion and tell me how WAR can replace a healer there. Try it. The amount of people complaining are limited to here, so I'm not sweating. It's just silly to see the same thing over and over with some expectation of change.
You also seem to forget how were playing a game where DPS is important for everyone. Tell me what happens for DPS checks when healers don't do DPS at all. Why is it that we have things like Green DPS, Blue DPS, and normal DPS. This is the game it is, it's been said earlier but if you want a game where healing is 100% of the thing you do, you're in the wrong game.
If it was an actual problem it would've been quickly fixed, it hasn't. Plenty of high end content where healers are needed generally. Let me know when healers are replaced in overall DF and PF by tanks, and not just people failing to normal mechanics or dying to enrage. Then you can say we have a problem. Until then, find an actual problem. Or don't and keep wasting your time. Up to you~. I'll continue to help healers out with having smooth runs though, the Healer strike is going so well after all that queues haven't changed one bit.
