Answer to question 1... My team is actually stronger than what you mentioned in A. with having a squad where I could name a 7* minimum starting line-up for every player and have 6* and 5* reserves. But A non the less.
As for success its A again, My closest rivals in my league lost again today which means I am now 20 points infront in the table.
However with my current feelings towards the game, It's likely my team will decline back down towards 'B' for both in the next few seasons as I can't go and get large amounts of tokens and invest in the squad forever.
