I would introduce a harder mode. Once you get past level 60, the end game is just too easy. Each shrine knight encounter as you go down into the underground library should have a Lucavi form or at least Lucavi style minions. The fight with vormav and subsequently ajora could benefit from some minions to make it harder. I would also encourage the remake to include the tactics advance story if possible. Playing those old advance games on the big screen would be nice.
