Blizzard implemented a few valuable hotfixes for their action RPG Diablo 3 this weekend. For starters, monsters will do a lot less damage in cooperative games.
Previously, D3 increased monster damage as more people joined your game. However, that won't happen anymore. Monster health will continue to scale, though, so cooperative isn't a complete cakewalk.
This change is understandable. It's not as though players became more durable if they were with friends. The result was that monsters would rip through them on co-op. At higher level games, cooperative could become more of a hassle than just playing solo. Ultimately, Blizzard didn't put co-op in the game so players wouldn't use it.
The patch also introduces a few other bug fixes. Player will no longer be able to turn in the same quest over and over and keep collecting rewards - you filthy cheaters. Furthermore, the pots in Act I and vases in Act IV will drop less gold. I suppose they want to make gold in shorter supply before the real auction money house goes live.
The last fix is a spoiler for those of you who haven't finished the D3 campaign yet, so be warned. It seems that Tyrael, when following you into battle, will no longer have collision so players and enemies alike can walk through him. That should make him a bit less annoying to have around.
All of these fixes should be live now. No word of accompanying downtime.
