Ye but you have reservs...you can train 1 guy with 2x 1% cond lose and it will count for training...
As I said it is probably a way to benefit active players cuz if you click betwen matches you should have advantage versus teams or players who dont even login...
Just my opinion about it...
I dont use rest aswell unless I have 2 matches in few hour gap

I usually use those free rest I get(you get cca 25 from adverts) but when there is no more you can click player and click + on condition and you will have few more there
