Oh, absolutely not. As both someone that both enjoys multiclassing and enjoys powergaming, I would never assert that.Note that a player could enjoy that as only one of many things they want, and many players like flexing system mastery within constraints, even if (often especially if) it means they don't overshadow other players. Once you get a knack for systems, it's hard to un-see the synergies that exist.
In other words: multiclassing doesn't mean munchkin.
