group invites whispers (not battlenet whispers) all seem massively delayed to point if inviting somone to help them get a mob tag the mobs dead and 20 more before the invite goes through or the whisper.
Also the mail system seems very delayed i tried to send my alt 2 gold to buy his level 20 skills and it lituarly wouldnt send after clicking send i logged out and back in and it had sent the mail but i got no confirmation of it sending
