I agree with Wraiven 100% and it shocks me that there aren't more people that do.
Leaving warzone for rage quitting is the same thing as leaving for a GF pop so y bother removing it at all? Doesn't make any sense to me. My solution for my 50 was queue GF and didn't even bother PVP'ing at all in protest.
This post below make a nice point though about a possible change that would benefit both parties but it isn't a complete solution.
What you quoted doesn't work because each time you queue for both, you are putting yourself at the bottom of two lists, one of which moves MUCH faster than the other. As a DPS queuing for both every time would result in you literally never getting a FP pop (at least on JC).
