So I'd like to make my one millionth "I totally called it" post about Leahblo, because frankly I have no other claim to fame. Whether or not you lesser folk acknowledge my awesomeness is up to you. But my thread on this was the FIRST.
*puts on sunglasses*
I'm gonna say no to Leahablo and yes to Adriablo...
Q: Will there be more PvP modes besides arena mode?
The developers found that PvP in Diablo II mostly split players up for fear of getting ganked, meaning more players were playing in private games than playing together in public ones. This led to a focus on on a dedicated PvP mode with dedicated PvP support, the arena, and a PvP progression system. However, more PvP modes are being considered, and Jay Wilson even said that they are looking into a dueling option similar to Diablo II, although nothing concrete is yet known and they aren't sure if such a mode will make the initial release.
This is probably only real interesting thing I got out of Blizzcon beside collectors edition. Hopefully they do put in Diablo 2 style dueling or at least mid game option of dueling for as long as you want and not just 1 match.
Well I thought he brought up a good point while talking about builds that guilds make it so you have someone to answer to, which can restrict experimentation. I'd definitely say guild support would be good, but just talking to people through battle.net and using chat channels isn't terrible, just obviously not ideal.
