i see what you are saying but this is really what the market section of the forum is for. must people that actually care about marketing will check the forums as well as the market tab because, it's on the same site, so why wouldn't you. if this was added there would of course be people trying to make a profit and put up their 'buying prices' for items very low, this is the same reason why higher priced items in the market do not get sold until there aren't as many of that item being sold. this is not to say that the market tab is useless either, but really, the only benefit of this suggestion is so people wont have to transfer tc? as if that's a hard thing to do.
(try not to assume what someone means by what they say either, no one is saying the market section should be taken away. just like how you are (hopefully) not saying that the market forum should be taken away)
hope that made some sense, it's l8
