I have 62,5% resilience now. People of my class and spec in the best gear possible have 67,5%. I get blown up with no chance to the point that it's almost laughable by people in Malevolent Elite. I could expect to have around 67,5% if I could somehow get the best gear possible tomorrow. This is an increase in effective health of around 136k. Sounds like a lot, maybe, but in today's amount of burst, especially what a Warrior can put out with his super-skill swifty macro, it's 1 more hit from an ability. And I'd get that from going from half 1/1 half 0/1 Dreadful to 2/2 Malevolent Elite.
Tell me why people bother to play healers, again? Or better yet, convince me not to abandon any healer that isn't a shaman or paladin?
