Don't quit ! A good co-op can understand that you must wait 8 days for the Marie board , if they can't undestand this you should look for a good co-op . You can't expect find always new content at a point it will all become a daily task as you progress but you play to finish the task and have good time with your co-op , participate in events which Zynga gives us a lot. Good luck !
Simply ignore it. There is nothing special about any rank in league. Zynga could make a more fair system but it would mean that you don't spend money on keys ( keys you spend on items to be higher in fair ). If you join later in a fair I mean 1 or 2 days after you finish fair ( ignore all fair things in FV for a while) you will be matched with other low farm / inactive players. Of course it would mean less time for fair but since you do "250.000" you could easy be in the top 3.
@Irraya@Rambling Rose It is true that a part of this category are cheaters but I have seen many other lower levels cheating. Especially in the last leaderboard event and sometimes in fair.. Level 70 with 1 workstation of each at gold having millions of points. Meanwhile 2 level 299 (me and a other player) struggling for 2nd place.
