Expand the perk system for more diverse and committing gameplay.
I would love to see more interesting perks that create new ways to play. Many great perk ideas from the community have already been suggested. I don't think perks are too hard to implement either, they don't require art/animation etc which can take months to create.
Some example perks:
-Backstabber- Increase damage when attacking the backs of an enemy when using knives would be interesting.
-Alchemist- Fire bombs and Smoke bombs have increased radius and longer duration.
-Pickpocket- Punching an enemy makes then drop an item they aren't holding
-Medic- Revive teammates with a healing kit
We need more committing perks that create playstyles.
Archers for example have two perks that they can commit to be better with their weapon. Same goes for the engineers with their smith perk, it's a great way to make a character that is distinctively better at one thing...
