Good server security that doesn't allow practically anyone to steal your gil while you're logged in without being able to do anything about it except wait until someone addresses it one by one.

Oh and better security to stop teleporting and gathering hacks but you know, entitlement and all, if you don't like it leave, can I have your stuff (literally anyone can have it now even if you don't want them to), game was just released give them time, this is just beta phase 7 wait for phase 8, etc.
