Level 80s who single target groups of mobs

It is vague but let’s take a look at the definition of “impose”

Impose:
1. To force (an unwelcome decision or ruling) on someone.

So perhaps, if we say “use your AoE”, and the person did it, then it’s not imposing. But if he resisted, and documented via chat, “No i dont play that way”, then it’s an unwelcome decision already.

That would be the assumption but then you can also kick someone for "difference of playstyle" which throws a wrench into the whole thing because I would consider "refusing to use aoes" as a "difference in playstyle". This is the issue with such a vague ToS, which of the two takes priority here? Do both apply? And what would be the GM judgement if you were reported for it?
