My opinion on difficulty.

Actually, IMO, Players 8 can be easier. Once you get used to playing at that difficulty, it is hard to go back to players 1. I also tend to be some ways behind in terms of map to char level. For instance, I recently started Act 2 at Level 19, while normally one would be level 12. So, when I am fighting Radament it is with 5-7 levels advantage. Monster HP scale up, but if you have a hireling or summon a valkyrie their HP scale up too, while the damage that monsters do stays the same. The upside is that drops are supposedly better to compensate 8 players (not quite that good, though but better). I think more monsters spawn as well. You won't kill as fast as players 1, but your NPC will survive better and be more useful. When you fight bosses, your support NPC take a huge penalty in being able to damage the boss, and the boss hits the NPC much harder. In that case, it may be better to play at Players 1.
