She got rulebooked twice by other teams because her team was super stacked. The rulebook states that a team is only allowed 2 "current pro players" and she had 3 Marvel Rivals pros. The rulebook doesn't care about Marvel Rivals pro status since the game is so new and only counts "current pro" status as being an Overwatch pro in the past year.
Another team tried to rulebook her by saying Hogz should be counted as a pro since he was the coach of an Overwatch pro team in the past year, which she allowed. They were upset that she was allowed to keep all 3 players despite this because Supergomez isn't counted as a "current" Overwatch pro. Supergomez was on the Team Colombia team for the Overwatch World Cup but that was in 2023, so that exceeds the 1 year limit. Meanwhile she also recruited Sabooboo, who fulfilled their "maximum S0 Marvel Rivals plat rank" status but was a pro Valorant player in the past year. Sabooboo and another one of the plat players on her team were told to stop at plat rank for S0 so they can maintain that slot.
Doki assembled the fucking Avengers roster and other teams are pissed because she abused loopholes. Even worse is that if you win every match 1 day and get first place, each player on your team gets $5k. Meanwhile the recent official Marvel Rivals tournament, 1st place was less than $1k for each player and it was like a month long tournament. So the Marvel Rivals pros on her team are going to fucking molest the teams that were "oh, I'll invite other content creators onto my team!" that are all silver-plat rank at best. There's a few other stacked teams in the tournament, so she's hoping for at least 4th, but her rulelawyering pissed off some other streamers in the tournament. She didn't solely pick the pros because she wanted a stacked team but because she has been queueing with them in competitive and they helped her get top 500, so they were her first picks.
