So boring, you won't do good like them, you need to adapt your team to their best agents not Ctrl C + Ctrl V a comp and not use the util of the comp correctly (Fúria Koi)
If teams saw this G2 comp and decided to try it but they play worse with this comp and decided to use this comp despite it not working then this is confirmation bias
Split comp specifically was first played by Sen and G2 played it with Astra instead of Omen, they changed into Omen at Bangkok after they got 13-4d by Sen at Kickoff. Give the credit where its due
