Nice feedback! I felt that Glass Cannon had a pretty big impact for our ranger on my last playthrough, though. I had an experience similar to yours, though, where it didn't really change the game much; Warlord usually nets you the same as the benefits you get out of Glass Cannon, without the downsides.
I still feel that Zombie needs a buff in a major way, though I feel it could be fixed with some fire absorption spells.
Otherwise, you're dead on. I think that most of the challenge will be in Tactician Mode, though, which will hopefully be harder this time around. I'd totally love to take the "Nudie Run" talent if it gave a good benefit, though! Like, an increased chance of looting cheese whenever you search barrels and such. Might be too strong like that, though, given the reputation that cheese has in DOS classic.
