I'm going through the updates, I don't really know all the changes so I'm just listing the most important stuffs.
Ebrdmg from min 100 max 115 changed to min 75 max 86. Weight from 5 to 8. Ammo decreased by about 50%.
The crossbow seems to deal just as much damage and the same headshotmultiplier as before with only 2x cost (i might have missed something since like I said I don't know where to look (or well I do but I can't look through every single value^^))
Chainsaw deals the same damage.
Can the Mac10 be op or slightly op? A good friend of mine said that he had no problems taking down a suicidal fleshpound with it (solo mode though). Anyway, it's got 25-35 dmg (compared to bullpup 16-26 or Ak47 35-45), with a firerate of 0.052 (compared to bullpup 0.1 and ak47 0.109), recoilwise it's got about the same as bullpup (i'm not really sure how the recoil stuff works). Also if i got it right it's got about double DOT compared to flamer, but im not sure here either.
Oh yeah also, law costs 3000 now and demoperk got 70% discount. It deals the same damage but now with 600 blastradius instead of 500. So a 20% increased blastradius.
Edit1: Looks like scar got quite a punch there. Damage nerfed from 75-85 down to 50-57, same rate of fire and recoil.
Now I'm really going to bed If I messed up somewhere and wrote wrong values please correct me, I'm just trying to help.
