MMO = Massively Multiplayer Online game.

By definition, it's meant for the masses. You play 10 hours a day? The mass doesn't, you're screwed. Complain as much as you want, you're still screwed. Try to gather people like you to make you point appear more appreciated? Won't work, you're part of a very small minority. Whatever you try, your playstyle is screwed. Change it and have fun, move along and do something else or be forever displeased with upcoming games.

No sane person will ever develop a MMO for players who play 10 hours a day for 3 years. Every unique dungeon which could be completed in an hour takes months to build. So let say 10 unique dungeons a day = about a year a work (assuming there is few elements reused). A year of developer work for a day in the life of a no-life rusher.

So 10 hours par day for 3 years, there are 365 days a year, so 1095 days in 3 years. Therefore, it would take like 1095 years to build a MMO to satisfy a no-life rusher for 3 years.
