Walk it off is a very good talent IF you don't want to put any points into Willpower and Bodybuilding. A decent substitue for sinking points into defenses stats when you want to make a pure damage warrior or rogue.
All in all, most talents really aren't worth taking and should just use your talent points to trade for ability points/stat points. Which also brings up another point that I don't even want to get into right now...
I don't disagree that one fewer turn of negative status effects would be a nice perk to have. It's just that I can see so many downsides to having one less turn of
positive status effects that it just doesn't seem worth it.
I have to agree that a number of talents don't seem worth taking. That wouldn't be so noticeable if there were more to choose from. (Although yes, just having more Talents wouldn't fix the problem of some of them sucking.)
