How do you define (meaningful) choice?

[Shurrikhan]

I mean you were still allowed to use healing spells in cleric as same as you can use combos without the step beforehand

So, the same as... another non-choice?

Let's not mistake finger-traps with actual choices. If there is no use case, ever, for the given action, it literally cannot be a choice, only a mistake. The ability to make more mistakes does not inherently mean more choice.

Like you can do almost any content with just 1-1-1-1 combos so I assume every combo is just bloat.

You do see how purposely doing 10% output with otherwise optimal gameplay (same actions, but 10% the stats) is not the same as hitting only one button repeatedly (not that you'd have changed much for healer GCDs), yes?

The latter would have higher output, yes, than someone making the "choice", as you called it, to attack without Cleric Stance or heal with it on, but it's literally only that -- neutered stats. You have equal access to that "choice" now by just stripping naked upon entering the instance.
