While I understand that zeni believes their current IP logging system to be flawless, like every MMO developer in history, the choice to show ACCOUNT NAMES for pretty much every in game social action is beyond foolish to me. You have given away 50% of our initial security to anyone who happens to own a pencil and a game client.
I was very surprised, and quite frankly, disturbed, when the account-name-for-everything system went into full effect. Any guild member, friend, or mail recipient/sender that any of us come into contact with has the potential to store our account name....
You know, those account names where you offer no other form of protection except a password.... and we all know how easy passwords are to break these days...
Please, please, please! Give us authenticators, or embed a system to use the google authenticators, or anything! Something!
The number of 'gold sellers' alone currently ingame is enough reason to make any experienced MMO player want to run for the hills. It's only a matter of time until they start targeting guild leaders and high volume traders.
Zeni.... Handle this!
OP is incorrect that knowing someone's login name is half the security. More like 25%.
