Random combat is the number one thing that makes me drop a game.

Its annoying, it happens too often, it always interrupts me when I want to do something else, and it is too repetitive.

This is why I stopped playing a lot of JRPGs. The other thing I drop them for is when combat only has a single song and always starts with the exact same intro, like what happened with Dragon Quest 11 or whatever it was that I played.
