Love this update!
Now with the Perks:
"Scoot N' Shoot" both look like very good choices right of the bat. though i guess i would choose "Scoot n' Shoot" at start for the aiming mobility, i would certainly give "Quickdraw" a try, and might even find the increased switch speed even better. we shall see!
"Rhythm Method" i can see being a big hit for players with excellent aiming and can hit a rapemode skrake's head off with it. or for me, Fleshpounds when doing their rage animation since im not that good at aiming.
I'll just go with "Bone Breaker"
"Speed Load'n" is most likely just Tactical Reload with a Gunslinger flair. and that is fine since i quite enjoy TacReload on both Commando and Support. Though being able to shoot a line of trash zeds with one shot is certainly gunslinger too!
"Center Mass" and the other skill are quite similar, but the kneecapping one looks like a greater risk and reward type perk. might go for that. Legshots!
Im gonna have to try out these Advanced Training/Zedtime perks before i can have an opinion on them for now.
Okay, now what would the Nailbomb's advantage be? looks like massive number of shrapnel that can fill up a room. maybe even larger splash then the frag but lesser blast damage. relying on the shrap for dealing pain.
