For just one second, think like a developer who, in his best interest, needs to keep people playing this game to keep their job and afford their livelihood:
1) This game is not developed to be "fair"
2) This game is no developed to be "skill oriented"
This game is designed to keep people playing it, so how do they do it?
1) Ask players to grind multiple sets of gear. About this they know two things: a) people will complain about it, but b) people will do it.
2) Reward players for investing time into the game. Offering small incremental upgrades for investing tens or hundreds of hours makes people think "why bother?". Offering larger, more significant upgrades gives people much more incentive to grind them out - and remain subbed.
What most people who don't think beyond their own keyboard miss is this: their are one million plus people playing this game, and among them there are probably thousands of different playstyles - BW (or any other developer) needs to ask themselves: how do appeal to the greatest amount of people to keep them subbed.
After playing MMO's for going on 12 years now (and of course this is opinion), I believe an extremely, extremely small number of players would attempt to resort to the "lower PVP time sink by shifting it to a skill based not gear based system" if they were sitting in the developers chair.
