That depends on first, your target players. Hardcore players would see this as a wall to overcome. And it wouldn't really bother casuals who only play now and then.
Second, business model. To a money hunger company, yeah this is basically shooting yourself in the foot. But if you're just making a game for others to enjoy, it's just a unique feature plus I think the goddess said she was the one who created the game.....so the company could just be a front with her seeing who best had the skills to serve her needs. But yes, if I personally made a MMO....I would NOT think to add such a feature, the lvl down maybe but not a 3 day wait penalty.
Unrelated, but the first time I seen (or remember seeing) a manga where they solely used the character's breasts for all interactions. That was interesting at first....but I can see it getting old quick. So hopefully they only do so once in a while.
