[b]0 to 100: [/b] Health / Weapon: Scale linearly... Flinch and handling / reload Grenade / Melee: Diminishing returns after 70 Super: The more you invest, the more you get. Max out at 100 Class: Don't know how Class scales... Seems to be more linear than Grenade and Meleee. 100 is a good target, but anything will work. [b]100 to 200: [/b] Health: 160, 170 and 200 are cut offs for health regen. 170 is fine for most players. Weapon / Class: Bonus damage and overshield scale linearly up to 200 Grenade/ Melee/ super: Never used, so don't know. Would not recommend running that high unless you have a specific build in mind A basic build might be 170 Health, 70 Melee, 70 Grenade, 100 super, 100 Class, and near 0 weapons.
