True, people wanted tanks to tank and healers to heal. But you're forgetting acc is not only about dps, at least for SCH.
It's fun, because while I was trying to down SephEX with my static, so much shit went down, and had to heal so much because people died, that I was nearly MP starved and guess what I missed?
Energy Drain. All tree of them. Atherflow on CD. So, do I shoot myself in the head losing the fairy that's actually helping me heal to get 2k MP back -and maybe miss Energy Drains again-, or burn the stacks into an indomitibility (if it's not on cd for whatever reason) and two Lustrates, being forced to use succor again, and be MP starved again, and wait till Dissipation buff goes down so I can summon the fairy again (for the awesome price of 2k MP), and wait some more for Aetherflow to be up again?
Shit happens. And if I wipe at 5% because I was OOM because my EDs missed, I'm going to be extremely pissed.
The acc problem is riddiculus, because I could meld crit+ss/pie into my raid gear and be more efficient as a healer (what they're actually asking I suppose), or meld acc to, let alone dps, be almost sure I get my MP back everytime I try, and be effectively efficient, because no MP no party.
It's not a choice. It's like they're putting your lunch (that you got yourself) on a pillar and telling you you can try getting it as you are -but it might fall down while you get it-, or go buy a net or something to be sure to get it back. Or, if you don't like it, I suppose you can go get something else to eat.
And before someone says a SCH shouldn't be MP starved, I'll say that 1. it's thanks to ED and 2. There's a lot of raid damage going down in new content, and while learning the fight it CAN happen to be MP starved.
I won't complain as much is they actually solve this -but still complain, because acc requirement are stupid (acc is stupid by itself, and so is parry), and while 3.0-3.1 was more on player skills (can you tank this and hold hate and mitigate properly without Tank Stance on? Can you find room to DPS without killing the whole party because you didn't heal in time?), this time is locked behind gear, and how much money you have.
I won't be surprised if we see an increase of gil buying, either.
