Again, if you only have the buffs in the hideout, then I don't believe anyone would actually bid for the hideout, and if you remove all the class specific buffs, I don't think anyone would bid for it at 700, maybe 100 since you can get all those buffs by logging in a couple of other accounts.
It would therefore only be logical if only a few class specific buffs would be removed. One of the buffs I would agree on removing would be energy coat, and in return, a class specific link to be integrated.
