It's currently P2Blizzard2P (one of the peers hosts, just all connections are trafficked through Blizz servers). What about allowing players to play against players on the same subnet to just skip the Blizzard part of that is a huge redesign?
The part where the players are connected directly instead of via battle.net servers??
If you wouldn't call this a major architecture change, what would you classify as a major change?
