I don´t like the recent changes. You need faaaar too many points to move up to a higher tier now. Not helpful that some wins only give you 4 points while some defeats take away 50 Elo points.
Higher Elo point range means that you cannot progress any more. You mostly get players with lower ratings which means that you need much more wins to even keep your rating.
Better do not play at all!
This is why prefer tourney to be honest, It's hard to get to Z place and I feel with efc you need expensive cards to win . I don't play it seriously anymore but it was nice before I even managed to get high scores in this new one but I can never get enough to go even higher .
