when you say you are satisfied with the overall mob density you must be talking about keep and arreat crate maps (ie the areas that people run and reload none stop to level)? cause the rest of the other areas feel pretty empty like the towers and the other areas
the fun part of diablo in general is being able to kill stuff... not run around 80% of the time to find stuff to kill or reloading 1 section of an act non stop cause the rest of the other areas have next to no mobs to kill
I have been playing other games and the encounters with enemies FAR surpass the likes of Diablo 3. Even Act 3.
MikeAkaJB is right. Sure there are some parts of act 3 that are good but the rest is just as lacking as act one.... The BEST act.
That is the act that everyone got in the beta and raved and carried on how good the game was. Little did they see act 2 or 3 or dismal act 4.
Sooooo...... The sooner you guys (at Blizzard) get over your idea of "this is fun" and "this is balance" and "this will make the game last longer", the sooner you will focus on what makes it fun (e.g. LOTS more monsters and places to kill monsters with awesome loot that doesn't sub-par everything else on the market or under-par everything so hard that it's laughable.) and the soon it will be the Diablo we will be happy to call Diablo 3.
Last thing. Everything you guys (at Blizzard) have done to try to "prolong" the playability if this game, the more you have upset players and made the game a worser experience overall. The last dev blog was awesome and seems you guys have noticed this. If you listen to your fans and give them what they want, they will come back time and time again wanting MOOOOORE. :D
