The issue isn't the amount of attribute points you get (and in the original you got a lot more skill points essentially from bonuses anyhow) but that pooling into two main attributes severely weakened your character overall.
Combined with the fact that items that gave you multiple primary attributes were uncommon, meaning that you are further depleting your effectiveness.
So if they gave you 1, 2, 3, or 4 extra... it would just boil down to the same event that any point not put into your primary attribute is only diluting your overall combat effectiveness.
In D:OS on the higher difficulties, hybrids just didn't cut it. IMO. IOW they weren't a viable choice at all. What I'm arguing for is that going hybrid might still not be viable for anyone
but the PC. It would only make the PC more effective. More effective as a single class character, too? Yes. But if you go past the point where you have to be single class just to get by, going hybrid actually has its advantages (in a 4 person party to boot). No 1 single character can duke it out without support in a party-based game, no matter how good he is at his class.
