I'm sorry but its the player who has failed not the game. You should not be thinking of efficiency while playing a GAME. You should be thinking "Am I having fun?" Its not about how fast you can complete a dungeon. It's about the ambiance and fun…
This game is far from underpopulated. Everywhere i go i see crap tons of players. .... I've only been playing for 2 weeks and I would say that population is not one of its problems. Bots and gold sellers well that's an issue.
