These days, you can link 20 or 30, maybe more accounts to a game center or Google account.
You can have one faction in its entirety on one device.
Yeah, I've already done it.
Before you knock it, consider the advantages of one WD streak team accessible from three or four devices.
Or, you and four or five TRUSTED associates can comprise an ENTIRE faction.
You are no longer required to be part of some silly social experiment.
If you have an older device (or devices), you can easily access these games from a newer, faster, more powerful device.
