I fear that frustration pushes you to claim a test server

if we provided a team environment with the fruits of their work not finished (or construction) and buggy, it would be worse for them than what we had to exit the game because we would take this as a true version .
we're just impatient.

when the system is developed and run in the mechanisms of the game then yes at this point can be tested effectively without making conclusion (like that will happen on FFXI).
But now it's really not the time, the game has yet to prove a lot.
