I actually started searching for the paper until I was rememberd by a friend that when I went to Denmark in a cruise boat I decided "While inside" the cruise to have a look at what to get for a tournament, then suddenly a gust of wind came through the window and the paper slip out of my hands and went outside through a door that was open and it went in the seas... that same day I bought my first 5th Edtion of orks just to get the points cost per model... Urgh horrible day... nowdays I use the Ipad for my army-lists. Sorry.

Get some temporary strenght boosts as the 2nd strongest Ork in the faction and toss the Warboss off of a cliff.
Sounds orky.

I think that stat idea should leave out the getting bigger part (because reasons already said in this thread) I think it should be something like for every kill the nob gains a very small stat boost
EX: melee kills give 2 points and ranged kills give 1 point
this would be like the whole stronger through combat that orks do
