Assault True Grit:
Remove global cooldown so technique can be used at anytime.
Remove activation delay of skill because it prevents you from committing to any other action.

Change perk tree to encourage specialization of class and add more distinct play styles and encourage min maxing of builds.

Change the item wheel so that any item can be mapped in any place so that items are more relevant to the play style of the preset that is active. Forced to keep shell casing to throw as an Assault for stealth play makes zero sense. Or Bandages when bandages should be automatically swapped to in the event you are out of syringes and critically injured. Or change item wheel to category based selection where the button is held and then ranks/types of items can be cycled through per bay if the appropriate bay is selected.

Sharpshooter Armor Buster:
Instead of loading 3 separate distinct rounds into the gun directly from the chamber. The sharpshooter should simply remove the magazine in the gun and insert a magazine of still 3 rounds that are armor piercing making the skill to be less tedious more likely to be used with other weapons depending on the situation.

Should be able to sacrifice 1 primary weapon slot for 1 perk slot max of 1.
