There were 3 broken perks known as early as the first week of release
Hit the Deck
Stone Wall
Ninja
None of them were fixed as of the "comprehensive patch"
Oh yes because those were huge issues.... note sarcasm.
Take your excuse to start &)*&)*@ about sniper rifles else where. There are a dozens of topics for that.
I'm not familiar with those perks. What are they about and what's wrong?
Stonewall gives +5 DT while your using melee/unarmed weapons instead of just against those weapons no matter what your equipped with.
Hit the Deck apparently suffers the same problem I hear. It increases your DT by 50% while equipped with explosive weapons instead of against them. Though some people report the perk not working at all, go figure.
Ninja fails to provide the proper critical chance bonus.
