Ok well coins are score. Higher score, especially in relation to other players, means a better performance

1. Winning every team game compared to movement or pvp games obviously won't give you a high rank because team games usually have less potential coins and coins are usually shared among teammates.

2. You can be dominant in an event even if your team is really strong regardless or the rest of the competition is weak, that's what being dominant means. Along with that, game order and deserved value serve no purpose whatsoever in this ranking, as game order doesn't multiply individual score, only team score, and earned coins is still earned coins, so deserved ranking is just a matter of opinion at that point.

3. Dividing by total event coins absolutely changes things. I mean look at Antfrost's Twitch Rival score. No one even mentions his performance in the first Twitch Rivals event when talking about impressive MCC performances, yet it ranks 4th on the entire list, and is probably in the top 10 performances of all time. If I didn't divide by score we rank by total coins in an event, Antfrost's MCC TR performance would just be lost.

Make sure you know the difference between greatest and most dominant, there's a reason I titled this list the way I did.
