A pure char would be filling 1 role per turn and would have those points spent in weapon dmg or saving throws, while the hybrid would have the flexibility to choose wich role to fill in a round, but without that extra point in dmg or savin throws.
This. You trade flexibility for raw power. Nothing wrong with it, game works fine with it (I never experienced problems with hybrids - and I play a lot of them in different combinations), so no need to change. In fact the flexibility makes them stronger (= more useful) during the game.
Never change a running system. Period.
