I think this should be "Account" option not character. Cuz i need spend 30$ to get premium on 3 chars? Thats too much for me where i earn 300$ per month. Every games have "account prermium option, not one character."
I very much agree with this, if you wanted to promote faction loyalty you could make it so its only same faction toons on the account, but since rp is across all toons on an account it would make more sense to have the items them self effect all the toons. I believe more people would be willing to fork out the money to get premium or the storage expansion if it had a larger impact on their game play. (more cash spent in cash shop for you)
