(Apologises if the format is off, writing this on a phone)
Ever since rank has been introduced to FvF, I have read comments from the community who aren't satisfied with the current Ranking System. The matchmaking feels uneven/unfair and the queue times are long due to the game population. It doesn't help that some players prefer to only play in private matches making the public queue even longer (not that I blame them).
Some things from the community have complain about are that they feel the gain/loss of points to be unfair, people leaving games to preserve their rank, people stressing about climbing the ranks and people using cheats (though imo cheaters seem to be a rarer case). All these things are harming the game's life in the long term and seeing comments from people who are done with the game due to these reasons is disheartening.
I suggest that FvF should scrap the whole Ranking System and either bring back level matchmaking or something similar. The problem with level matchmaking back then was that exp and money gain was a 1/3 of the current payout now. High lvl would often get matched with low lvls because most players were people who stuck with game and new people trying the game. High level accounts also had access to the most or all cards at near/Max lvl while lower lvl accounts would lose more often against them and recieve like 20 dollars and like 30-50 exp for losing. Now that exp and money gain is basically triple the amount, newer players are able to get more cards and lvl up faster.
Instead of deleting the rank icons, they can be recycled to a similar format akin to promotions from a game called Deep Rock Galatic. Rank icons could be use to indicate how long someone has played. Some examples can be like a white border is given at lvl 0, then 1 star at lvl 25, 2 stars at lvl 50, 3 stars at lvl 75 then bronze at lvl 100 then repeat. (Numbers could be changed if that's too long)
Overall I think these changes would help the game in the long run as I believe FvF should be a game that you play because you want to have fun and not grinding for the next rank.
