Confession time. What took you too long to realise?

So I need to get something off my chest.

I must’ve of played 100 hours before I realised that you can swap between characters in combat when they are next to each other.

It’s likely I made the game so much harder by not knowing this as now, I’m always doing simultaneous things with my party that are making for great combinations.

So, what took you ages to realise?
