Let me clarify a few things here you guys are seriously missing.
Whats wrong in people attaining +15 not by lucky but by actually playing the game? Why are You guys afraid the game pvp might become skill based and not gear based? Is it so bad for a game to become skill based? By the End of its life everyone was full +15 either way. DBO system as it isn't hard at all lol. It's just frustrating and punishing for no real reason and demands lucky rather then anything else.
My sugestion is the best so far for DBO, it is very easy to control that on the dev side. They can decide how hard and how long would be to be +15 , instead of relying on luck.
PS: Early game SK are really strong ( why do you guys think budokai had 5 sks in one party?) , they HK anyone that is badly geared. Whats the fun about this?
