Twistzz most likely won't challenge for top 3 ever in his career. He was never even the second best player in Liquid.
This notion of rating players by aim should end at that, just rating their aim (and people mostly rate the aim aestethic, or flashiness, which isnt the whole picture of aim). The flashiness of a players aim doesnt directly indicate whether a player will even win a straight 1v1 duel, with timing, gamesense, movement, focus/ reaction time being a factor in every single aim duel. Then comes impact of a player overall, with his decision making, knowledge, instinct, communication etc. which make Twistzz not even a top 30 player this year.
Since the Berlin Major in 2019, the following players have had a better rating than Twistzz against top 10 opposition with at least 80 maps vs top 10 played:
ZywOo, s1mple, device, NiKo, ropz, KSCERATO, HEN1, Elige, electronic, yuurih, syrsoN, Brollan, Krimz, stavn, Magisk, dupreeh, CeRq, Brehze, frozen, cadian, XANTARES, NAF, woxic, Ethan, niko, huNter-, TeSes, jks, broky and coldzera.
30 players have been better than him in the past 17 months. 30. And you here think he is gonna be in top 3 contention because he has nice smooth aim. Cool. 0.95 Impact vs top 20 opposition in 134 maps in 2020.
And he isnt even the best aimer, NiKo, ZywOo, s1mple are a tier above him.
Fun fact: FaZe have the 2 of the most overrated players in the world, Twistzz and broky! Then a honorable mention rain, who people still rate highly, despite him having literally A SINGLE TOURNAMENT over 1.14 rating since June 2019! A 1.01 rating against top 10 in 2020, its very obvious that rain hasnt been good in quite some time now.
FaZe will be about at the same level as with NiKo in 2020.
