Evidence 1:
The KC coach said in the interview that Scream wanted to be IGL (something the coach didnt plan for) but he at least managed to trade that for him accepting to play duelists.
Evidence 2:
Sliggy said many times on stream that he left TL because he wanted a proper IGL but Scream prefered being IGL and didnt want to sign a new player to fill that role. But they signed Nivera instead. His non igl brother. Even Link later left for the same reason ("team structure"). And they still didnt sign an IGL
Evidence 3:
Scream goes on a twitter campaign arguing duelists suck and surprise surprise... KC stopped playing them for a long while in that time.
Edit:
Evidence 4: They kept using strats from TL. Forcing them through despite them repeatedly not working. Like the raze astra breach trap play they did 100 times. Worked like one time. Or some specific buys that just do not work and fuck eco.
You must be deliberately looking away to not see the obvious. But you are moroccan so no shock you are biased.
