Look. You shouldn't choose this as your hill to die upon, because you're wrong.Kobu said:Who?
I don't doubt that you understand a one pip bonus equals a 5% chance, but you aren't looking at anything economically, which is what I'm trying to show. I'm not going to waste time demonstrating basic probability which no one disagrees on.
Look at it another way--at 20th level, the human bonus is still one pip when anyone can get at least a five pip bonus from a few different sources. 10 or more pips from different sources will probably not be uncommon. The +1s make up a very small amount of the total defenses the higher the levels get. It never scales while neck slot items, powers, etc. do, thus its relative value decreases.
It's not a horrible bonus, but it's certainly nothing I would brag about.
Let me illustrate it this way.
Suppose you have a character who attacks at +8 versus my character's AC of 19. You hit on an 11+. If you gain +1 to attack, now you hit on a 10+. Your damage output increased by 10%.
Now lets change things.
Suppose you have a character who attacks at +10,008 versus my character's AC of 10,019. You hit on an 11+. If you gain +1 to attack, now you hit on a 10+. Your damage output increased by 10%.
See? Its all the same. Not everything in the game auto-scales this way, but defenses most certainly do.
