Taken from the valor post:
"If you’ve already made plans and sank your Valor, don’t fret! As of this announcement, and even if you have 0 Valor currently, you still have enough time to cap out at 3000 Valor before patch 5.2 goes live. (It’s math!)"
1000 valor per week means 3 weeks in order to cap. It looks like we have an extra 7 days (at least) before the patch is released. Good news for us. Heroic Protectors and Heroic Tsulong should die this week, leaving us with roughly 6 to 7 lockouts to get the big baddie dead.
