Ranked 2014 FAQ hasn't been updated.

Since This is the only place I can see with all of the FAQ's about ranked. I feel it should get updated to what the 2015 season brings to us. Most notably is the question about ranked decay, it states that you will lose points if you're not playing ranked for 28 days in silver and gold+, but now points only decay in platinum+.
