I think the game is very easy, I think it should be very easy, I find the game very easy. I've been playing MMOs since final fantasy 11 came out in the US, as main form of entertainment, I am disabled, and I spend 80 of my day in an mmo of some sort.
Basically Nothing, outside of a raid, in game should Require another soul. Raids by their nature should require people, but nothing else should, I got really tired of being the drg looking for a party for six hours to go kill a single mob, never again will I accept content that is denied to a solo player.
Oh, and before anyone asks, why I bother to play an MMO, because I like a self continuing non static world, that gives me a sense of progression and permanence.
