... I'm sure there are loads more, and I think that different behaviours of enemies like this can make the combat much more interesting than enemies simply running up to hack at your shins.
Agreed.
I want more tactics in combat. Alternatively, there should be an option to fight only dumber creatures that can't jump, if you're not good at it. ?
But even guards that constantly circle the building forever when you are on the roof? Give me a break.
Also some AI should create faulty jump attempts that result in physics based falls.
