i am pritty sure: red packs are wasted if you just use em to get your fasttrainers on the pitch again. 5 redpacks give you 40% condition if you use it right after serverrestart. compared to 5 greens it's realy low. it only pays out if your player is injured for 7 days or more. i save my red packs for important games. and if my fasttrainers get injured i just give them a rest an if they are healthy again, i spend some greens to make him catch up again.
