i have no idea what point of my post you are refering to.I fail to see what's "not true".
I'm saying i switched to another lvl 10 player because i knew sooner or later the level 10 i had drops..
This part is not true. There is no way to tell which level 10 will drop first because the drops are random.
Anyway, it was no criticism to your idea, it was just a comment to try to help, sharing an explanation (about the randomness of the drops) that it seemed relevant at the moment here.
Your idea actually makes more sense than the way things really are on BB's current staff system. That's why I said before and say again, I hope they change this soon...
