not as simple as that, tanks and healers do in a sense but it's challenge comes from reacting to what the bosses do, casual dungeons often lack specific mechanics for these two roles so you do pretty much the same thing throughout, raids/trials are more thought out for those roles. Dps have longer rotations because essentially dealing damage is the end goal and can be done in a variety of ways, healing and tanking however is fairly limited in how you can implement what they are required to do, like healing damage or holding aggro this is even more the case for reducing damage. most 'mechanics in casual content is designed for dps to react to.
