I currently am using two ID's, and do not cheat. Hate two a day Worlds because gameplanning around work sucks!!! (Yes I am in two two a day Worlds until this cycle ends in those two worlds, and then 1 a day worlds only.)
I don't have the time or energy to use one to scout, or compete with the other, although I am not against my D3 in exhibition against myself and my D2 team.
