How I think pro perks should be

[UnicornCan115]

I believe that perks should be leveled up like a weapon. The Regular version of the perk does one thing. After a challenge (Assassin Pro I for example) you unlock a new feature for that perk.

Let's use an example.

I'm using Assassin. I am invisible to enemy UAVs.

Assassin Pro I-Kill 50 enemies while they have a UAV or Advanced UAV in the air. Unlocks no red crosshairs or red name when an enemy sees me.

Assassin Pro II- Kill 25 enemies within proximity of their Portable radar (IW could use something else). Unlocks invisibility to Portable radar.

Assassin Pro III-Kill 25 people that see you on their heartbeat sensor. Unlocks invisibilty to heartbeat sensor.

I'm just saying that it may help balance the game so that people just don't suddenly have these extra abilities by just destroying 30 aircraft.
