Rebalancing perks.

Currently, scavenger basically is the best perk for all of the weapons (other than Isolator+Model), and I find myself always choosing over other perks.
I suggest we beef up the other perks, so that people would actually use them.
Here are a few of my suggestions:

Juggernaut - user takes only 1/3 bullet damage (used to to take 2/3), and has reduced fall damage taken by 50%.

Flak Jacket - user takes 50% of grenade damage (50 dmg), and all damage taken from other explosive sources is reduced to 50%, including crossbow and Ray gun.

Martyrdom - grenade explodes after 10 ticks of it dropping.

Hardline - Killstreaks cost 3 kills less (in CoD it's 1, but it is rendered useless by scavenger).

Speed - food bar drains 50% slower, speed stacks in infected game mode.

Stopping power - weapons deal 2 hearts extra damage instead of 1.

Before crying about how overpowered this is, look at scavenger and tell me that it isn't worth using it. I think we need to make other perks capable of outperforming scavenger in certain situations. I understand how overpowered this can be when paired up with the corect weapon, but you won't be able to resupply ammunition when using any of these.

 

This would require a perk point system that I already suggested. Many people called it balanced.

 

It was buy able in the old 2.0 Beta.

Marathon - infinite sprint
Speed - faster move speed
Marathon is still more versatile.
NOTE: Buffed Hardline on your suggestion.

The only powerful perk in the game is scavenger. And as you know, these cost real money.

I'm sorry I didn't think everyone would like this post every time they read it.

Stackable speed, it seems legit. I just hope it isn't mistaken for blink like sugar in WarZ.

 

That would be overpowered.
You would become the scout from TF2.
Infinite speed 1 .-.
