LOL! Before the patch, my big guildies dropped own so I could get in top 3 for WB and get a plan. And I got an IH chest plan that I will not be able to use for a while. Since the patch however, they let me get top 3 again and I got a champs chest plan. Something I needed and was able to craft right away.

So perhaps it is rigged, and the devs are trying to send a message to the people who take top 3 day after day. That they need to let their lower guildies take top 3 spots for plans for a few. And then maybe they will drop what you top spots need again. Just a thought, and I am likely wrong. But then again, maybe not.
