The taint mechanics got tweaked a little in all three incarnations too, but it really doesn't matter.

All three versions of the class are inherently, horribly overpowered and utterly reek of power-gaming cheese.

I only ever brought the thing up for completeness' sake.

Who knows? the op's DM might be willing to work with him on incorporating a house-ruled to functional version of the class into the game. Kind of a long-shot, IMO, but what the heck.
