Perk System has been updated. Check it out!

Teh reason why there are 3 perks is because that's how Call of Duty does it.

The only reason why WaW had 4 Tiers was because they added battlefield vehicles on the map.

What do you mean by it's not Ideal?

I created and organized the system myself (with community help)...I just used the Perk System 2.0 information from the 1st multiplayer leak (don't care if it's true or not)

I don't really think it needs tinkering (maybe Scavenger), because players using Scavenger have a chance to replenish what they want, and it won't be annoying like in MW2. The reasons are, because this perk system has too many protections against equipment, so even if you camp, people would know where you are (except MW2, where you were able to combine Scavenger and Cold-Blooded and resupply everytime and the only counter was SitRep). Besides, they can ONLY earn the equipment IF and ONLY IF the fallen enemy had an equipment still in their inventory, but when do you see that? Rarely, because everyone uses their equipment. Same with grenades. To help prevent constant nade spams, you can only resupply them depending if the fallen enemy had Lethals or Tacticals left in their inventory. This also applies to the noobtubes, where the fallen enemy has to have any underslung attachment equipped when they died to replenish them.

Lightweight, Sleight of Hand, and Marathon combo isn't OP at all. If you think of Black Ops, you had that combo and it wasn't bad at all. Remember, don't look at the perks as if you will earn both pro versions, because you cannot. You can only choose 1 of these Pro abilties, so it's practically still having 1 base ability and 1 pro ability, except you have a choice for your pro.
