Can there be some kind of gold share between characters? So if you have max gold on one of your characters, you can transfer some to a lower level character. That might be too overpowered, but it's a cool idea I've been wanting for a long time.
That would definitely be cool. Seems a little bit overpowered though- like if you have a level 110 wizard with max gold and transfer to like a level 5.
I can't think of a reason why not but I'm still a newbie so I could be missing something... What I do is simply put any unwanted drops into the shared bank and then 'whichever' wizard is low on gold can take it and sell it.
Farming by teamup can add up a lot at times too. Even if the first player doesn't let anyone hit I often will get something in the drops.
