If you start with 80, and you get 1 per 3 levels, leveling won't change a thing about your character
I admit that when put to paper it does sound a bit less attractive and some refactoring might be needed, but you have to keep in mind that the value of a single point does go up as you advance, rather than diminish.
The game looks to be targeting around level 30 as endgame(level 8 is ~25%), and those extra 10 points will, combined with gear and other sources, still add up to nice chunk of your power.
As an example, an average D&D campaign has you start with about 70, depending on how you split them in point buy, and you only get 5 extra before you hit level cap.
