S5 Weekly cap honor - Can you increase it ? Dead battlegrounds

We are week 3 or 4, we got +/- a good gear. That means we have less items to buy except Boxes ?
So let's assume you opened all your boxes for the week, stacked 75k honor, what then ? We are locked

I have no interest at doing battlegrounds anymore because my honor is caped, and I think a lot are facing this issue. Can you unlock honor cap so we can just spam battlegrounds for a reason ?
We are locked until next wednesday, no point doing pvp activities. Before we could farm wintergrasp marks for alts, now it's just a mess. Blackrock is less interesting to play on
