That still doesn't cover all that you said. 10 different things 20 sec in advance then spam a bunch of different abilities. 20 sec in advance and your atonement is already gone, thus your argument is already invalid. Then after the "10 different things" that you are already doing, what are the "bunch of different abilities" that you speak of? You're making it sound like way more than it actually is and I'm not sure if you're ignorant or just building a mountain out of a mole hill.
Yes, druids spend 1 button to tranq, yes, we do have to prep a bit more. The difference is, we actually have to learn fights and think for ourselves!!! GASP! What a concept!!!! We don't just go "oh well it looks like some people are taking a lot of damage, let me push a button." We actually learn when big damage is going to happen and prep for it, we research boss fights and watch videos and you know, actually do and pay attention to mechanics.
I'm glad that disc got harder to play, it makes people who think for themselves actually shine at what they play and the people who zone out during a boss fight will give up and go play another 1-2 button class.
