Sorry if this has been mentioned before but the only thing I am missing in PL is some sort of in-game mail system. There are two main reasons this would be useful:
1: sending gear to alts ie if my enchantress gets a nice archer drop I could mail it to my archer. As far as I'm aware you can't do this now. If I'm wrong, please let me know how it's done.
2: Trading with other players. If I want to send something to a friend who would find it useful I currently would have to meet up with them. That's fine if they aren't in the middle of a dungeon or offline. It would be great to mail another player something with a COD option (cash on delivery).

Ideally one would be able to mail items (gear, potions etc), gold, and maybe even platinum although I can see the devs may have a problem with the latter and unserstandably so.

Do let me know what you think, if it's possible, and/or if you can already do it and old blondie here has just missed that feature 
