I remember reading that a while back, but it still confuses me why people are using that amount because it's only relevant for people the people who already have the extra accounts at that price since (I assume) you can't do that anymore. For the purposes of this discussion I'd think using $50 as the comparison value makes more sense.
A bit off topic but still relevant to the whole cost discussion: Where are people getting the $30 per account figure? I thought the game was going to be $50. While it doesn't have any effect on issue of alts being better than VIP in the long run, that's still a pretty significant cost increase.
