Cuz majority of polearm people bitch about every nerf on them, and push for the nerfs on others.
probably just becuase its the most versatile weapon, so almost everyone is using it.
theres maybe what... 10-20 people out of the some 20,000 people using polearms that have more then an ounce of skill.
(watch your back for dainsters, that dude is sick)
Key to stopping rolly pole-ys is blocking their two go-to's overhand, and stab.
They are piss scared of hitting teammates, and hate walls, so pretty much 4 out of 5 swings are going to be over or under hand.
I dont think they realize how weak this makes polearms, unless your alone with 5 enemies in a field.
Endurance.
Cuz thats how dainsters gets you, you can block his over underhands 10 times he just keeps jump spin stabbing till he lands it.
