If you didn't know, you CAN filter out legendaries from GTS which is very helpful
Yeah, but when the filter system is used, if you attempt to trade with someone the game crashes and you have to restart.
That atleast has happened every time I've used the filter-system and attempted to trade with someone while it's on, and I've read that others have had similar problems.
I think what would be helpful with the GTS is if it had a time-out system for trades. If your trade has been up there for example, 5 days, then it will be removed if it hasn't traded yet.
At the least that would stop a lot of the impossible/unreasonable trades that fill up the GTS from filling up pages of trades.
I'm just very very thankful that the GTS no longer lists just 6 trades at any time that can't be refreshed.
Or at the bare minimum, if the filter systems would actually let you trade.
