Since you are restricted to one drop a week in crystal tower, can i ask what is to stop people from the following:

Let's say the gear you want drops, you greed or need it and you get it.
So, the player tells himself, "hmmm now I am locked out from obtaining anymore gear for the week."
"Ok, i'll just leave the alliance/party/duty"
The result is then that the alliance/party is left having to look for a replacement.

Or, am i understanding this wrong?
