1. Create a reinforcement mechanic for areas (goblin camp, swamp, blighted village, etc...)
This reinforcement mechanic shouldn't be triggered by the AI itself (example: the goblin drums, too easily put out) but by the number of rounds a combat is going on. The more rounds it goes, the more enemies appear. It would stop the kiting and would make combat much more tactical.
The game is probably already maxed out for the number of enemies it can show and move around, due to both scenery/camera design and AI limitations. To show more enemies than we see now, the combat arenas would need to be larger, and fights would be longer due to AI processing delays on enemy turns.
I suppose the game could draw in more waves of enemies after X number are killed, but people are already complaining about how long some of the larger fights take.
2. Give the AI the ability to use the verticality better
There should be some mobs specialized in jumping up and down very easily to create a sense of emergency. At the moment, you can camp on your roof and you are ok.
I agree with this. Anything the player can do, enemies should be able to do as well. If you can climb on a roof using just manual methods (i.e. not teleporting), then enemy melee fighters should be able to follow you up there. This may be a work in progress with path finding. And maybe the number of inaccessible places you can reach by teleporting with Misty Step should be reduced.
