Say what you want about Boaster and yes I have had my doubts, but:
EMEA Stage 2 Challangers 2021: 2nd
[higher placed IGL: Scream?]
VCT Reykjavik 2021: 2nd
[higher placed IGL: Shahzam]
VCT Berlin 2021: didn't qualify
Champions 2021: 5th-8th
[higher placed IGL: Bonecold, Scream?, Klaus, Redgar]
EMEA Stage 1 2022: 3rd
(2nd best truly) [higher placed IGL: ANGE1]
Masters Reykjavik 2022: 2 stand-ins so doesnt count, was one of the favorites
EMEA Stage 2 2022: 1st
Masters Copenhagen: 4th
[higher placed IGL: ANGE1, Benkai, FNS]
Champions 2022: 5th-6th
[higher placed IGL: saadhaak, FNS, stax?, ANGE1]
so all in all Fnatic has been one of the best and most consistently good teams in Valorant with Boaster. Also Boaster individually has usually had decent/ok international performances. He is one of the most proven IGLs in Valorant and still is. More proven than guys like Vanity that people like to praise for some reason. Ofc you can't put all on IGL because Fnatic has had good rosters, but just to give idea.
