What may seem like an excessive practice, multiboxing is getting more popular.
The art of playing multiple accounts at the same time. For example - a cleric and a warrior - both controlled by you. Heals that land when you need them. Double the power but double the demands on your already stretched attention. This is a community of people who control two, three, four, five, even ten or more characters at the same time.
The cost of setup is too steep for my blood, but given everything, I would love to give it a shot.

I’ve run 5 WoW characters on a single box, no alt tabbing required (unless one dies, of course)
