Hello

I reached level 25, and have very good friends playing on 42 and 31 levels.
The other day, I wanted to play a frienship game against one of them, starting to trash talk him saying I would have an easy victory....I thought it was like in association's games..but no.
Why shouldn't it be possible to play friendship games as we play association's games, I mean, without the stars gap?
It would be much more interesting, and we could play against friend of ourselves, we will never challenge in league or cup competitions.
