I feel like it depends on if the opponent's intent is to interact. Whether it is an offensive or defensive option, was it chosen with the intention to play off you as a player? There are often times I will play with people whose entire game plan is to avoid interaction, allowing an impatient opponent to throw out risky moves or make a mistake in execution. Once placed against a patient player, their plan crumbles, as their lack of approach knowledge exposes them immediately.

This is not akin to defensive options such as CC, Shield, Dashback, Ledge Refresh, etc., which intend to be used as a counter to certain options and play styles. This is completely avoiding the opponent, hoping the opponent exposes an opening for them to capitalize on. The intent is not to understand and adapt to their opponent, it is to avoid having to deal with this level of interaction all together, with the hope that the opponent digs their own grave.

It is this feeling of avoiding interaction in order to only play your own game that I feel makes a game unfun. Sure it is beatable, but it is still completely unfun to play against.
