I liked the TBC-through-WoD PvP gearing system because an alt was never too far off of being extremely competitive in battlegrounds. Now, to be at the top of the battleground power curve you've just got to be exceptionally geared in general, which takes way more effort than a few days dedicated to battlegrounds to get Near-BiS with just a bit of arena farm for full BiS for PvP. I used to spend more than half of my time on this game playing random bgs on alts that I'd get geared in honor gear but now I barely even bother to do them on my main because I'm not able to be at the top of the PvP power gear curve with just random BGs. Somebody who only gets gear from BGs is just fodder for anybody who does any remotely high level PvE content.
