Never once had this nor seen it in the hours of beta videos I watched. In fact, I've never heard anyone else mention it. I honestly have no idea what you're referring to. Sounds like the problem is with your client.This leaves you with constant cliff hanger moments, like entering a story area in a dungeon only to be greeted with
"DOWNLOADING ADDITIONAL CONTENT".
Futhermore, I've played probably 5-8 hours and never encountered even the most minor of bugs nor seen any in beta videos. The only bugs I've seen are in BNET topics to specifically talk about bugs. D3 is in much better shape than SC2 at the same stage.
This is a bit different than StarCraft 2 delays. At first, Blizzard didn't want to mess with SP/PvE balancing for PvP so PvP was barely supported. Fans bitched incessantly. Then they decided to have some PvP specific balancing and now they want many arenas like SC2 maps. Basically, this time, unlike chat channel delays and whatever else, they've expanded their features instead of just delaying them.This "release mandatory features in some patch in two years instead of release" crap needs to go.
Thank God for that. Much like StarCraft, messing with the formula would have ruined it. I've played five or six high-quality Diablo clones and none of them came remotely close to Diablo II.However to me, its still quite the same Diablo and nothing ground breaking.
