Yes, take some time, but you'll eventually get it. I max'ed Prestige a month ago, now waiting the next season to keep grinding (I do it for the mounts).
I do as many WQs possible (usually 3 towers + 2 wpvp ones per day) and at least one BG victory per day (often a few losses) since the start of the expansion. At this rate, I get one prestige every 10 or so days. You'll get to Prestige 11 by the end of December/start of January.
