I understand your frustration regarding QTEs for I myself don't appreciate not being able to watch a cutscenes in peace, however the fact we have a turn-based game pretty much obviate this feeling in the sense we're not spectators but actors and that we're already involved in the fight.
Given the fact they're situationals, their role would mainly be to implement another kind of management.
The idea here was to take advantage of the time limit and exploit it as a kind of "ressource", though the term is improper I admit.
If anyone have a better idea (item-based management for example ?) I'd be glad to discuss it, but I sincerely think the use of the most powerful skills should be somehow limited.

Thanks for clarifying your thought anyway.
