This happened to me last night twice. Hate the key mappings... the group I play with just turned the loot windows off. It was a persistent issue the whole night.
I'd say regardless of when the servers come up, and hour later they will be bogged down then shortly thereafter die as a million people try the game for 20 minutes. First couple weeks are generally just bad for new MMO's...
It would be very nice. I think quite a few people will decide their class based on the ruleset and playstyle, and may ultimately be discouraged and stop playing when the rules suddenly change to match the PC Production version.
