Apart from that combat could be broken by spamming companion abilities once you unlocked them all.

That’s the big point for me. Ive seen another one play the game this way and I agree with that the combat can be broken this way. It propably is the most effective way to get through combats but its IMO not the must fun one and does not embrace the intended gameplay flow.id even go as far as saying that this way actually works against the intended vibe and since the combat is such a mayor gameplay part of the game I can see how a dissapointing combat might ruin the whole experience for you.

This strategy is one of the prime examples for me where adapt gamers will optimize the fun out of a game because they focus on efficiency rather than fun.
