I understand that you can put it in for seals; however, how is your need for seals greater than someone elses need for seals. If needing for seals was an appropriate understanding of the term 'need', then everyone would be able to need everything. A WHM can trade a Fending accessory in for seals just as easily as a Paladin.
Anyway, I don't strongly care for this issue. The gear is usually so low for the content time, that I'd rather gear up alts via other methods. That said, I agree more with the OP than others.
