You base your opinion that there is no DR cap on someone using more DR beating some other people using similar gear?
It's been tested and proven. My barb uses a legit ccs without eth rune and beats barbs with 915iths all the time. Does that mean my sword is better than a 915 ith? Well, it has lower damage, and no eth rune, and lacks many useful mods that iths have.

/w *thesuck for duels.
I use only legit but will be happy to take anyone on 1v1 in a friendly duel =)
