D3 = geared up in 1/4 the time Did you know that with this game structure you get gear in 1/4 the time it would take in d2? Possibly less than that. While based on an assumption, it is logical to assume that it doesn't matter whether 1 person or 4 people are in a game and kill a boss, the number of items dropped for each player will be the same. Ex: kill this boss he drops 2 items for you, if two players are in the game both would receive 2 items due to the scaling of difficulty. Reducing the number of items dropped for each player when multiple individuals kill a boss is counter intuitive to the developer's "play with your friends" design strategy as well as it's a kind of punishment for killing in a party. Where I am going with this is that with a balanced group (4 different classes) presumably all with different item needs (for most slots) you can achieve gearing yourself 4x faster than you would solo. Using the math from above, let's say you are going for a legendary staff that drops off an end boss in bastion's keep. With a .5% drop rate on the item and 2 items dropped per kill, it would take you 100 kills to get the item (on average). Whereas, with 4 people in the game, that's 8 item rolls per kill, and a need to complete only 25 runs to get that item (on average). Therefore, running any dungeon without 4 people with you gimps your ability to get the items you want/need. Better start finding 3 other people you Trust/enjoy playing with!
