I am going to side with Dwoggurd and say it is pretty bad idea.

Incremental resist - I personally like it but I dont see any real purpose of doing this change.

Deathblow - Abernyte and many many other players (including me) think it have to go.
It served it's purpose nuking 2k hp Masters. Now it is incredibly unbalanced.

Some pointers:
1) Battles are all about destroying magi. But deathblow rarely changes the outcome of the fight between villager and mage.
2) It grants tremendous advantage against warrior_type classes who dont have dam_reduction options build into class (aka sanc).
3) Deathblow costs nothing. (Being villager has its drawbacks. But deathblow skill itself does not.)
4) Deathblow begs to be abused. Unscrupulous villager could easily repeately kill everybody in his pk (typically in middle ranks).
5) It forces enemies of Battle to resort to ganging.
6) Substitutes player skill for RND.

These arguments could go on and on.
But here is my proposal:
A) Replace current deathblow with manual_input owaza_type skill.
B) Dump the 'no-ganging' rule for berserkers. It never really worked and is constant point of complaints.

Reason for this - Every other cabal gangs. Some are even encouraged to this type of behavior. Berserkers are not supposed to... in exchange they are given DEATHBLOW.

Screw this. How about Ragers play by the same rules as everybody else?
