I'm sorry, of all the things I dislike about the game, this has got to be near the top. I understand the merits of it, but at the same time, am I the only one who has multiple people who use the same computer, and share the games?
Now I'm in the situation that because my partner and my son also play the game on this account, I have to move my stash loot back to my personal invent whenever I log out, for fear of them selling off anything that I might want to keep. As for my gold, (which I put a hell of a lot more effort into acquiring than they do), can be spent by either one of them on a whim.
I get the positives, I really do, and if I were the only one playing, I'm sure I would support the feature.
Everything about the game is geared towards the account, rather than the character.
Thats another thing, a 10 character limit. I get there is limited server space, but this is just another argument for making the game available offline.
