Everyone heard that .."Medbow, medbow, bla bla bla..."
But noone realy know who is that. I can show you.
Ofcourse you can play as medic-tank\blocker and your team will never wipe, but its so boring :)
So i prefer to play as badass medbow or even medzerk(chalenge_mode ON) and kill everything .. inc scrakes and fleshpounds. Its so fun to stay 1 VS ZEDS.
But! You still able to block\tank during medbow, if u want to. Ready? Here we go! HoE.

Loadout:
MEDBOW:Credits to: My own experience.

Make some predamage with any weapon. Then turn him into rage with xbow headshot. Then kill!
NOTE: Do not use xbow headshot as predamage.

Just watch...
Burning prevents rage. You can deal massive damage with any weapon, with any perk while fleshpound burning.
NOTE: make sure to reskin fleshpound to coil texture.

Here we go.
There is not a full list of exploits/bugs i know. I want to keep some of them because i do not use them and dont want to anybody use ... :)
Someone can call me a bagouser\exploiter, sure u can! BUT! Before you do that, Ask yourself:
"Who is most powerfull? Medbow with all of exploits or SharpShooter wiht xbow and 2 pistols\support with katana build?" I know an answer.. So please dont' :)
You can keep playing SS, what about me? Ima just trying to get some fun of this game!
