It's one thing to say they provide more granularity and there can be checks against the score rather than the bonus, but Dungeons & Dragons never does that!
D&D uses granularity all the time: +1 to an ability score per 4 levels, not wait until 8th level to see any change; +1 inherent bonus to an ability score per
wish spell, not wait until you can cast two concurrent
wish spells to gain any benefit; +1 Strength from the Strength domain granted power on 1st level, not wait until 2nd level to gain any benefit.
Immediate gratification counts for something. I'd rather get half my paycheck on Wednesday and half on Friday than get my whole paycheck on Friday. Heck, I'd rather get $10 on Wednesday and my entire paycheck minus $10 on Friday, even if $10 is virtually nothing compared to my total salary.
Otherwise, why not just cut character level in half and double up the benefits you gain each level? Then you don't have to add
half your level to anything. And the only price you have to pay is going twice as many game sessions without seeing any measurable character advancement.
Since the game only ever uses the bonus and since the bonus is tied to the score in a linear way, the score is redundant. Period.
As of 3.X, that statement is patently false. You need a 13 Wisdom to cast 3rd-level cleric spells. You need a 13 Strength to carry 50 pounds as a light load. Perhaps such things will change in 4e, but your absurd claim is that the game only
ever uses the bonus and, well, 3.X is part of everything ever in the history of the game.
And even if 4e does change things, nothing changes the argument about granularity. Sitting around waiting for a level divisible by a large number to get an ability modifier increase is less fun than waiting half that long to get an ability score increase, even if an ability score increase has minimal benefit in and of itself.
And incidentally, point buy only encourages even numbered stats because racial ability score modifiers are even. If and when races with odd ability score modifiers begin to appear, point buy using ability scores instead of ability modifiers gets much more interesting.
