All tunnel visioning leads to the same result, for every role, but the severity varies based on the content.

And like I said, it's the only role where a DPS rotation run counter to the role.
If that is the case, then it's because it was designed to be that way. It doesn't have to be designed to be that way.

It's simply a matter of risk assessment
What, that a player might end up making a mistake and or be a bad player, thereby potentially making something more difficult?
Again, things that, to you, Tanks and DPS are just allowed to be: problems. But healers? Nope, not allowed. Can't have anyone be learning to do better, can't have anyone deviating from being a Sylphie or else the DPS and Tanks might be mildly inconvenienced for not being allowed to be bad themselves.
Must babysit, must keep things fun for the others. Be strong Clarence. Do it for mother.

Yes there are reasons, and they are very GOOD reasons too.
From where I'm standing, your reasons are inconsequential and fail to take in the account any sort of nuance for learning, at the very least, but for other reasons as well. I'll let you figure those out on your own, since you should be able to follow the breadcrumbs to get there.
