I never had serious login issues in UO. Okay, I'm a newcomer, but I can live with login problems, I'm a network and system admin and I know they happen.
About the lag... my lag on UO is not worse nor better than the lag I have in any other online game. Just normal lag I'm used.
And the puzzle room, come on... this is not Puzzle Room Online, it's Ultima Online, an entire world, I can easily find something else to do until they fix that single, okay new and okay exciting, but still relatively small part of the game.
Now, about imbuing, nobody forces anyone to get to 120 skill points in a week. I train my crafters every now and then, no macroes, no UOA, I just stop training when I get bored, even if I only had a 0.1 gain. It's a game, not my second job.
If you quit, anyway, I applaud your proposition to trash all your stuff, expecially the gold. That will help stopping the inflation.
