Idea Combined Perks

Not all perks are equal, there are some dominant ones like stopping power, marathon/lightweight, and steady aim but some that are absolute trash. Some of them match pretty well so why not combine them?

Flak Jacket + Juggernaut = Juggernaut Pro This perk is just there two combined together they usually aren't used at all so combining them might make them more appealing to use over another perk

Grenadier + Danger Close = Grenadier Pro The problem with danger close is that you can only use it twice per life and after that it becomes useless. Grenadier is hardly used anyways since the grenades aren't very reliable so combining these two would allow more reliable grenades that can be used 4 times per life.

Scavenger + Bandolier = Scavenger Pro, yes scavenger is a good perk but it sacrifices too much defense and kill potential for sustain, the main problem with bandolier is it doesn't work when you first spawn in and also has the same problems as scavenger. Combining these won't make too much of a difference but it will make it very appealing for players who want to go on high killstreaks. Also in Modern Warfare 2 these perks are combined anyways.

These are current combinations Ice Bear came up for now but feel free to comment more ideas below.

 

Ice Bear says it can make kill time very fast and turn a deagle into a pocket sniper?

 

Ice Bear says it is not meant to be good with snipers just like most perks but better with assault rifles, SMGs, and pistols.

Update 2: Perk revamps
Lightweight: now eliminates fall damage completely. A minor change but one that would make it appealing to use over marathon.

Sleight of Hand: now combined with extended mags which increase magazine size by 50%. Snipers really don't have a perk that is ideal for them besides the mobility perks. Also, sleight of hand wasn't very useful considering weapon swap times are instant and trying to reload even if it is a reduced reload time instead of swapping weapons will often get you killed. With extended mags attached to this there is a good incentive to use this perk for snipers over marathon.
