Shared stash or mail system?

I would prefer for a stash system over the mailing system. Mail changed people on WoW. The 1 night mail couldnt be used the servers basically crashed, you have auction whores running back and fourth because they couldnt interact with the mail box. Spam in trade for god knows how long, screw it.. 1 shared stash throughout your entire account. Like guildwars had just not as gay please.
