Let's get the DPSing part out of the way... HELL NO LMAO. Throwing the same 3 or so spells is boring as all get out. I mean, you still do it, of course, but it isn't engaging in the least.

The healing itself walks a fine line between fun and frustration. There are instances in which everything is going well, too well, perhaps, and the level of engagement is kinda low, but as someone else pointed out earlier, it's when the struggle starts that you have to stay on your toes.

When you heal, you deal with the additional mechanic that is... well, people... lol. There are instances in which everything is so chaotic and stressful even, but these can be fun. Depends on your predisposition to those instances, I think. Some like the tiny adrenaline spike that comes with an unexpected death or mechanic screw-up, some don't. Some do in some instances and don't in others...
