It is easier to get a 5 star at the end of the season (who goes down to 4 star at the start of the next season) then it is to get a 4 star at the start of the season. I replace a ton of 3 star players for 5 star players at the end of last season and now I have a team full of 4 stars instead of 2 stars. and almost all of them I got for 1-2 tokens, which is WAAAAAAAAAAAAY better than the usual 10-15 tokens for a 4/5 star.
