How to take control of dc hero

When a player from my team quit, I try to play his hero. I can play but can't buy items for that hero or don't gain gold. Is there anyway I can take control of dc hero?

One more question. I see the color of members are different. For example, Atlas is red. Hades and XCO2 is blue. Sando is orange. Can anyone tell me what color represent what position? And also, do you only give those position to EU/US players? Is there any asian player who is a respected member? Sorry for my english. Also sorry for using members' names. (Atlas, Hades, XCO2 and Sando)

Red - Administrators
Blue - Moderators
Green - Veterans
Orange - Editors
Yellow - Normal

If they D/C you automatically gain control of the hero, unfortunately you can't take the gold they have or buy items for the hero.

You can sell their items however, giving your team so bonus gold if you wish, but that diminishes the usefulness of the character.

Yeah. In end game they often have enough items. I always had to buy a TP and give it to them though lol. And its hard to play two completely different heroes at the same time. o.o
