I think removing stuff that wastes time is nearly impossible. A large amount of the game is just wasting time, or put better, investing time with a reward for progression. It's just how well that time-sink is veiled and how tasty the carrot being dangled in front of the grind looks which justifies whether it is acceptable.

I felt there wasn't too much of that painful time-sink in 1.0 and most of those aspects have been addressed in interviews for 2.0, which has made me happy.

One of the main issues for me was that selling items to other players (ie MW/AH) took so long! Hopefully, in 2.0, working out how much something sells for and how often it sells will be easier to ascertain (and we wont have to rely on fansites or add-ons). In 1.0 I used to write a list of items I had available to sell on a spreadsheet, step over to the item search counter, record all the amounts, step back to my character and put them on sale. This took a good amount of my time whenever I got to log on and I'm looking forward to getting that time back in 2.0!

I do have a deeply thought-out suggestion for a new market system, but I'm looking forward to experiencing what the new team have programmed for 2.0 before I try to suggest my <ahem> 'better' way of doing it.

(well maybe that wasn't an entirely 'constructive' post per se, but at least I kept it positive..ish)
