So how I can share silver between characters in my team? If not, what the point of team?
Any other ways to benefit from multiple characters in one team?
You can not.
You might be able to put an item up for auction on 1 character, and then buy it from your 2nd as an indirect way of trading silver (I haven’t actually tried this so it may not work).
There is no point. 
You gain no benefit from having multiple characters.
Lol nice system. Such an progressive design of economy. Very social mmo game xD
Yeah, the current trading system is awful and we’re BEGGING for a change. Just see the amount of posts regarding this topic on the forums.
