They should really have had a single player mode

[Capita]

Interesting concept. It would be fun to be able to do some basic tasks, like leves or something, and then when you log in the data uploads and updates your character. It would probably be limited but it could still give options for people who can't or don't want to connect.

This would be REALLY easily exploitable. I can already think of a few client-side hacks that could upload to the server.
