I don't agree with the absolutely insane health, but I agree this is the way events should be played. Can't finish? Get stronger. Older accounts that can't attempt to complete didn't take advantage of the inflation like they should have by being active during the past Raid Boss's and case events and whatnot.

What I also don't agree with is the frequency of their upping the health. They're raising the health much faster than our stats are growing, so it has become an endless loop of gold spending to finish each event when it should be getting progressively easier.
