Look me topic about the pvp betting system. Thats a good suggestion. Further Don't expect blizzard to put much focus on pvp early on. This is mostly a pve game. But later on I expect many more pvp fun.
the pvp is "relativly" new as such, their not going to focus a large ammount on it at the moment.
The betting system sounds fairly cool however theres some option for "tipping" matches as such.
I think the pvp side of things will come along eventually, just give them time
I think way too many people are looking at Diablo 3 pvp as if it were on the same level as WoW pvp. They are not the same and will never be the same. People asking for pvp gear and the likes will be let down. That will never happen. The focus of diablo is coop game play and farming for gear. If they allow pvpers to get gear just for pvping then it goes against a fundamental aspect of the Diablo experience.
And I wouldn't get your hopes up that pvp is going to get the kind of love you hope it will. It is not as big a priority as some people in the community seem to think it is. I don't see them releasing tons of new pvp content like an MMO would. You are playing the game for free so in reality once you buy it they are under no obligation to continue to add content to it. And if they are adding content I would bet my money on it being pvm content since that is where the most people would experience it in a game like Diablo.
Some people try to relate to WoW immidiately because it's the biggest online game there is and some people will immidiately object and refuse any and all features which appeared in WoW because they grew tired of it but the fact remains that it's the most popular because many of these features are very enjoyable. People shouldn't rush to conclusion because somebody would like some similar battle arena thing like Battlegrounds in Diablo 3. Just think of the feature itself and not in relation to WoW
