If you just made a HC trade forum you would keep everyone happy.
Is it really that hard to keep all players happy by keeping trades out of the hardcore forum, but not having them ignored by putting them in a trade section spammed by sc playes and ignored by HC players.
Sorry, but I will continually post trades in the hardcore forum as that's what i paid to play until you actually bother to create a HC trade forum.
Heck you could have a sub section in the HC forum that trades could take place, so you don't have to create a whole new area.
Rocket science it isn't!
