Honestly what sane or GOOD DM whorth the title would sacrifice player enjoyment for the sake of having his way. I mean come on, what do you think wold happen to a PnP group, if the DM insisted on being right 100percent ofthe time and the players were not having fun?
No you are just being stubborn. Obviously "respec" is an MMO term while "retrain" or whatever the term is in the PBH2 is the PnP equivelant. FOr arguements sake, lets "presume that they are synonyms.
