If you have a lot of tokens, then negos can be a good way to get tested players. On top of that, you get all your T refunded if the offer's rejected. You can also use this to your own benefit... Train a player (easier if you play on computer, go to old version) so that he's 1sp (old system) off 6* and you may get good offers. Check out Nik's guide in "Tutorial and Guides" section
