maybe he should. just because the other ppl use the system doesnt make it right. that kind of logic is called bandwagoning.
tbh i dont see why they wouldnt want a system as described by the OP. blizz takes a cut of the profit for themselves. so the longer the auction goes the more they get. it would also make the seller happier for the same reason because they would get more as well.
basically it just ends the problem of auction sniping and allows ppl to continuously bid for it.
With time extensions you've traded one problem for another. Shill bidding would become much more problematic. I prefer the current system.
i dont see the problem here other then legal issues. if you bid up to the most you want to spend then still get outbid then you werent going to win anyway. in the case of shill bidding though whos to say they are doing it? those are some strong accusations after all, and you need some proof they are doing it to back up those kind of claims. aside from the fact that most people cant supply proof, the system now doesnt do anything to hinder shill bids. so there is no difference.
