Wow.
Sneak attack and Kael's power looks intensely Awesome.
Is the AI going to be able to use those correctly?
I am mopping up the drool as we speak.
The Impersonate Leader power, definitly not (switching between it and another computer player wouldnt accomplish much unless I wrote an entirely new AI process just for bad playing). But the hero is a powerful unit in its own right, so the AI won't have problems using him, it just wont sacrifice him to take control of a civ.
The sneak attack ability it will be fine with, it already declares war with players when its in their cultural borders and suffers being jumped out. It will just have the advantage of not being bumped.
