We have never said that. Please don't say we said things that aren't true..
THIS ^^^^^ is exactly why we don't do too many missions for the lower tier battles. Because the lower tier battles would be flooded with VERY experienced players, though NEW players do get protected MM even at 500 battles players get thrown in with people with thousands of battles and that is not particularly fun.
As for the CV meta, that is being addressed on WED with the new patch.
