I love the usefulness of the witch doctor(wd), getting to extend my troop's lives and then giving them a second unlife make for some interesting battles. But there seems to be an issue with the wd's AI; despite being upgraded to have an extended range, he stands and follows far too closely. Most recently I deployed him behind some gunners and brutes; he followed the brutes and proceeded to walk up to them to the point where he could reach out and use "lay on hands" (a D&D cleric spell if anyone is wondering). If the wd can be upgraded to increase his range, his follow distance should be decreased.
Agreed. In additin to his other issues (see my new post coming in a few mins), he follows too closely, and dies for it.
