The "arena" style just doesn't suite Diablo.
It's not dueling, at all, or even PKing. Which is why they renamed it, and they know that. It's just a giant ****-fest.
Again, very little player input besides who gets the first hit/stun then hit in.
We have no way to join specific rooms. Since they went with this linear Quest design and prevented Act jumping. Which also removed custom named games and instead uses the travesty that is known as matchmaking. Never good, not even on consoles. So now there's no way to join "Brawling" specific rooms.
To find people interested in "brawling." you have to either; A) know people who want to, and still actually play; B) Find people on these forums and friend them; C) take your chances and room hop until you find some people.
There's no risk. Absolutely none. You don't lose Gold, you don't lose Durability, HC Characters don't face permanent death. What's the point, really? Just hop in and OHK each other for a few minutes until the novelty of it wears off?
IDK who developed D3, because frankly, I don't care. But all you did was make take most of the WoW concepts and ideas, and apply them to the Diablo universe. Even with this so called "brawling."
Incredibly disappointed...again. :\
