That's easy to say. But with new players signing up, the first thing they look for is adding a player to help their squad. They haven't seen the impact of forking over such amounts on one player.
I agree with the holding period suggestion. I myself am very active in the TL. Mainly because I want to buy good players statswise for cheap. If I get them and find out they're not a match for my team (when I checked them via Assist!), I put them back out with no initial starting price. I'm not out to make a profit on them (if I do, that's great), they're just not what I'm looking for.
