Well, one of the formost reasons is the economy.

Everwhack's economy is slowly going down and down. Things are costing
less. There will be a point where steins of moggock will cost 25 PP, and
every newbie will have em. Mesh and cured silk will be available to
everyone. It doesn't have the get/lose/restock economy that UO has. It's
get, keep, never lose, accumulate.... So forth.

Verant continues to nerf the classes, to "Balance" them. They are doing
a peice of shit job of it. If they keep going at this rate, all of the
classes will be especially weak, fighting especially strong monsters. Sure,
this will be a challenge, but there comes to be a point where it gets
ludicrous.

I know this sounds rather silly, but seriously look at how the game started,
and how it is now?

Where are the differences? How have they changed? How have they changed
more towards my predictions? I saw a moggock stein for 900 pp one day. A
month later it was 255pp
