... No they wouldn't. They'd fail . REALLY HARD. If you up the difficulty curve, people aren't going to suddenly get better. You're just going to lose a lot of people who aren't that hardcore into the game. Raising the bar doesn't make the jumper jump higher, they have to be willing to put in the effort, and people who are just barely grazing it now aren't likely the kind who'd put in extra effort to hit the new standards. What will likely happen if you make healing harder is you're going to get more people playing DPS, or possibly tanks cause "healing is too much effort".
