You can now have friendlies with another team without bothering a well rested opponent, as the only one who will lose (condition, injuries etc) or gain (boosters, skill pts etc) anything will be the one who arranged the friendly. So instead of blocking friendlies, Nordeus opted for this which is quite fair IMO.
But then again, I seldom play friendly nowadays because I find that it is totally different game engine than competitive matches. Players do not perform the same way they would in competitive matches. This is based on the skill progress gained & condition lost during friendlies compared to competitive matches.
