The bleedbusters are a blessing imho.
We had all these fancy skills like ED, Exaltation, CI, Benison, Tetra, Veil, Protraction, Krasis, Haima, Aetherpact... but nobody needed them.
A friend of mine and I played a minigame of "dot uptime" when we both tanked on Hippo by constantly running into the water and trying to keep the Dropsy dot up as much as we could. It was a learning and intro event for people that didn't have any raid experience yet, mind you. Including the two healers. They didn't need to heal us at all. We were entirely fine with our selfheal while deliberately eating as much extra damage as we could.
Now healers finally have a good use for their single target heals. The only time I really used them was on bird add phase and when T/H got tethers on p4s part 1 to save aoe resources. Benison on each healer before the hit and more Rapture for Pinax, towers, orbs etc.
That's it. For an entire tier. At min ilvl no less.
And I find the reactions to the current raid tier quite amusing.
I've heard plenty of times how bleedbusters are a nightmare, how Tree is hell, how Carby's damage should be nerfed and so on. And when I hop into PF to help friends or get reclears on my alt, we frequently wipe to unavoidable back-to-back damage because on top of mitigation being bad in PF, many healers just don't heal in time and have no clue about when they press which button. It's rare to see a healer that at least has a general idea of when they use their big 2min/ 3min cooldown and do it somewhat consistently.
Quite recent example of this: my last Carby reclear party kept wiping to unavoidable damage and when I asked the WHM if he has a specific time for Lilybell, he first asked me which skill I mean. I used auto translate. Asked again, which skill that is supposed to be, told me to wait while he looks through his spellbook. Found it. Said "No idea. I just use something when I see a low HP bar". And that Temperance doesn't feel like it makes any difference so he doesn't use it. While we were getting one-shot through Kera + shields.
