Yet another increase in cost with no benefit gained. A definition of a proper legal contract is when both parties give up something and both parties gain something. A .05% does not sound like a lot but this is on everything, the sale price, the shipping and the taxes. Ebay could make much more revenue by making things easier for sellers and buyers to sell and buy. The below standard increases are a way to punish the "low value" sellers. Why? If they are scammers or just jerks, kick'em off the site. If you are new sellers and trying to work out the kinks of selling on ebay, encourage them, educate them, don't punish them.
Where is the give and take? Where is the mutual benefit? Ebay has to be profitable, sure. But, they should be open, communitive and engaging with the sellers and buyers.
