Anyone that played GoW2 would probably agree that it's an awesome gametype: satisfying mass mob kills, bragging rights, tons of replayability - think that'll all be just 100x more awesomer in D3!
1)Slaughter waves of mobs that ramp up in difficulty: find best class combinations,
try out builds,sense of progression
2)Tie to BNet achievements: team that reached highest wave, most kills/DPS, server firsts, etc
3)After lvl99,killing MegaUber Diablo, 10 000 Baal runs later, this'll offer end-game content that can never be "completed" (+very little dev work required, just randomly generate mobs)
In order to make this work:
1) There should be minimal item/exp gain. Maybe just give some reward after defeating a mini-boss every 10 waves or so to keep things interesting. Considering game balance, this mode should just be for fun/achievements
Thoughts?
