Please, don't compare mmo based in 2 factions like wow, rift, aion, Swotor, wh,...
Gran companies are like 3 reputations because you can join with others gc members in a dungeon.

Whichever way you look at it, it's a punishment against pvp players, more aggravated on legit pvp players. A wintrade will spend 130-200 hours again to use theirs gears and switch to another GC. A legit pvp player, look back and will say "oh no, more grindfest pug lottery, no thanks."

And then, the only choice is wintrade to avoid long queue, and random shits.
