I hope the retreat from combat works properly. It would help for the "immersiveness" I think. Imagine you're Conan sneaking into the caves of Thulsa Doom with your friends, but having to flee from superior numbers, leaving a carnage behind. Is better than all dying, reloading a save and restarting right ?
Yes, but it will be more immersive if you are not sure to be able to flee each time, if you might fail your retreat and be caught up.
