I just HAVE to butt into this convo and offer my opinion. (and I realize that I'm inviting all kindsa angry raving feedback....) Alla this discussion about cross-tier trades and zero or one star trades, etc. ... We're all thinking human beings who have this amazing feature of being able to make our own decisions.
Talking about trades being "unfair" doesn't make sense. A trade is a trade. Period. If you don't like a particular trade.....Don't. Take. It. Simple as that. Like you would buy the fresh veggies, not the rotton ones. Or you would buy avocados cuz you like 'em better than kale. (eeeuuuwww....kale.)
The only prob with them is that they clog up the trader. Like people putting up 9 thousand 50 unit trades instead of lumping them.
A side note: I WILL say that I'm befuddled by alla the zero-star trades being put up for sentient goods. Are people actually TAKING these??
OK: bring it on. I know that this is such a 'tetchy' issue that FSs actually make RULES about it.
