I've got to say; I am actually glad that on this item they limited them to 30 days. At least this leaves the possibility that if players do not like the OJ's, they can develop the costumes in the future without them!
(And players almost unanimously seem to be against the OJ's, so yay ..... at least the 30 day was attempted here).
I don't think they will make costumes in the future without the OJ's like you say...
Restrict it to the "vanity" feature and take away the massive statpoints, and you'll see only 1 or 2 people with the costumes.
Judging by the number of silly looking bees and penguins you see hanging around AH, not many people in Shaiya care about how their toons look. It's very apparent that the costumes are just for stats. They make AGE happy. They give the paying players uber stats to give them a huge advantage over everyone else, which makes them happy. They make non-paying players want to spend just so they can compete statwise. This is EXACTLY what Aeria wants. It's especially ridiculous that these costumes were allowed to be in the 1-15 zones.... Hey let's make the beginning zone even harder to participate in by requiring that everybody participate in EoM tiers!
It's like they are slowly trying to kick out everyone that plays this game for free. :\ I am in support of removing the costumes, or at least significantly reducing their OJ potential.
