Well, I know since I have the "entry" account, which is like. $2 cheaper or something, I can only have eight characters total (and only one per server). The "standard" gets ... 40 I think? And like.. eight per server I think. Even if they did something like this, it's more a money issue to save those $2 monthly (not much yes but it helps)... so while it's not a bad idea I don't think there would be any monetary incentive to add it.
