1) If it were to have a pricing per character they would have said it in red letters ( Extra character fee has not yet been determined yet)
2) If it were to be pricing per character they wouldn't make restriction on the Membership tiers for the amount of characters your allowed to create ( ex: Legacy 8, Entry 1)
3) Were getting Benefits here, they wouldn't just "keep us in the loop" of things. All things that would be related to pricing would either have been said, or have the words " X has not been established as of yet" lines.
In short, YES we are getting 8 CHARA'S for 1 prices as it says.
Edit: Also, Why would anyone Choose the Standard Option when you can just to the Entry for 1 Chara?
If the Extra Charas packaged required you to pay more money up front to use those extra characters.. then what would be the point of the package deal in the first place? :/ Common logic...
