Be able to make money bet's in pvp arena.
As for the armor and weapons. It can be kits such As: Iron, Gold, Diamond and leather.
It's like dice, but you fight.
It's basecly making Duel's, you call some one on a duel, you make your rules of the fight ( what can be used in your fight), make your bet's (I think money bet's is enuf) and fight. The winner get's the loser's money that they betted on.
I was thinking about team fights, like 2vs2; 3vs3, but I didn't find a way to make it work. As for the armor kit's. I think after dueling they (of course) get removed (when the fight is over and the winner gets his/her prize) or you can make it with out kit's and just let people use the stuff that they can us. Of course I was thinking about people who have high gear of H1+. I think that's the only reason I started thinking about kit's, so there will be a balanced fight.
Why bets (only money). I read most comment's about people wanting more pvp and I think I'm not the only one who noticed. That the server got even less people after the last update. We can only guess why and try to improve. As about bet's: Some players were talking about "risk of lose" (when you have a chance losing a rare item), some were suggesting to turn keep inventory off of pvp arena. I think money bet's on pvp, can be a small interesting factor. Since then people can fight and also earn something, not the h1+ items or items of the player, but only the money there were betting on.
