I don't think you're ever really stuck in this game, as far as having a character that's able to complete it.
The concept of re-speccing is always a tricky one. While I always think that I would prefer a system that let me make minor changes often as you suggest, as opposed to wholesale re-spec, I feel like it would be pretty exploitable in this game. For instance you mention Pet Pal, an ability that is situationally useful, but not as useful as other perks that pay dividends much more often. What's to stop someone from swapping out that talent to use for those specific situations, then swapping it back out for a more general purpose one as soon as it's not needed?
To be honest i dont Think he meant to be able to respec, more to be able to remove a wrongfully put point during level up, for example if you put a point into streangth but you were meant to put it into intellegence, you should be able to remove the point you put in.
