Part of the reason I've decided to take a break from this game is that I'm not willing to spend another 80 hours grinding battlegrounds for the sake of achieving equal footing with my opponents in PvP. I think it's a faulty system, however I understand the reasoning behind it. Blizzard strings up carrots and manufactures desires for the sake of month-to-month subscriptions. When the hard-core kids have all caught-up with the available gear, Blizz makes up new gear and the cycle repeats.
However, I think it sucks for players who don't want to invest days and days of solid boredom (SEE: Alterac Valley) just so that they can meaningfully participate in the one aspect of the game they really enjoy (SEE: Arena).
Honestly, I'd rather that gear was eliminated and skill/spec would have a greater influence over our performance.
