I'm stuck at the downloader but I imagine it will let me in later this morning. Some people have already got a few hours play in but a great many are stuck either downloading the game or at the log in page.
Let me offer a few last tips for launch day:
- watch for gold AH bargains. Prices will be very cheap today as no one has any money.
- level will probably be the main determinant of wealth. Don't try to level in magic find or gold find gear.
- do collect +exp gear as it is not shared with your party.
- look out for gold and green items. These weren't in Beta but were a huge element in previous games.
- buy some + run speed boots from the Auction House as soon as possible.
