I don't know about other championships, but italian "Calcio A" (... -.-' hem they didn't get the rights not even for the name of the league...) is way too much unbalanced: after 23 played matches Juvent... ehm "PIEMONTE CALCIO" (omg... didn't get the rights also for one of the most prestigious team in the world...) is winning 22 matches... OH com'on. So the player is supposed to win EVERY single match to try to win the league. Really?!
Real life: Matches played 36, Juve won 26 and is champion. 83 points.
FIFA: ending league with something like 115 points.
Destroy all the fun to play.
