So i've seen a few of these threads made over the last few days. Just going to throw in my 2 cents

A few ideas i'd like to see are:

The EM limit raised

Buy it now

Snipe Bid Protection

The ability to remove an auction you posted

An option to state you are seeking a particular artifact and/or resource

Feel free to add on and whatnot.

A price per item upper limit so that it no longer becomes storage.

Yeah, as I stated in another thread a upper limit to stop the storage, and to slow down the credit transfer that can take place between multi accounts. Upper limit could be 5% or 10% more then the average price for the artifacts. If the upper limit was reached then it would become a buy it now. If the same accounts were hitting the upper limits on items on the same accounts selling then flag them.
