Who told you that btw? May i ask what do you do in RL, and how big is the knowledge regarding computer games? Pardon me but i can assume that you know close to 0. So no that statement is a lie.
dude...dont go in there..im an IT aswell, and thing is you cant do anything regarding arena, it's part of the core game, plus, if they never did that on china, they're not going to do anything here, plus the only thing that counts on arena is your iniciative, the rest, you have pretty much the same stats regarding power mostly. If you lose, it's because of smart plays, or teams synergy, or even iniciative, doesnt have to do anything with being strong or weak. I've won against people with cursed hidan and susanoo sasuke, so if you're being salty about losing, dont blame oasis, blame yourself.
