Behind the scenes at WoW Insider, we've been talking a lot about scenarios recently, for various reasons - some of which we hope to be able to soon share! In those discussions, I relatively quickly had to come out and admit, yeah, I kind of hate scenarios. It's not that I think there's anything actually bad about them. Maybe individual scenarios have certain annoying mechanics, I honestly haven't done enough of them to know. But I kind of dread doing them, and avoid them for the most part, and there is a very simple reason why: when I first go into one, I don't necessarily know what I'm supposed to be doing.
I cannot communicate how much I despise that feeling. It's why I love being a healer. Here is your job as a healer, in any dungeon or raid ever: you stay out of the bad stuff on the ground and you play Rejuvenation (or Holy Light, or Healing Wave, or whatever) whack-a-mole with health bars. It's great. It's structured and straightforward and it's always the same. Sometimes there are additional mechanics you have to be aware of but, here's the thing - boss needs interrupts? Not a healer's job. Mobs need kiting? Not a healer's job. Turtles need kicking? Not a healer's job. Boxes need clicking? Not a healer's job (usually).
