I always /lol'd at people who have this mindset. It is pretty much pointless and a waste of time to do all of the factions at the same time for the simple fact that you can't earn enough VP to spend on all of those factions gear. Work on 1-2 factions to revered and along the way you've earned the VP to buy the gear during the rep gind. You will reach revered with each faction long before you earn enough VP to buy the gear from them all. Work on another 1-2 and along the way you'v earned enough to buy the gear. Now I can see with 5.2 how people might feel that they need to do all of the factions at the same time since the gear cost will drop in half (for the majority of them anyway).
