You didn't understood me properly. I'm not making an apology of dipping (and stopping it entirely is very very hard anyway). What i'm saying is that multiclassing serves many purposes, even if we label a one time dipping for a perk and multiple times dipping for powergaming as "Illegitimate purposes", that still leaves other uses that have nothing to do with it, namely keeping two paths at the same time, and changing the path of your character because of redemption, corruption, enlightment or any other success in-game. What I say is that those restrictions hurt those purposes unnecessarily, you cannot change the class of your character organically once it becomes logical, you have to have it heavily scripted from the very beginning. Some "hybrids" of two classes won't fit very well with the most stereotypical image of their base classes and many will be very much impossible given those constraints. Those cases were the ones I was talking about when I said "every game, every table", if the rule has to be waived every 8 out of 10 cases, then it probably should be best left turned off and only used when necessary (i.e. when excessive dipping with powergaming purposes is a problem)
