Demon1 used to solo duelist in 3 maps Ascent, Lotus, Pearl and Haven. They always perma banned two maps but I don't remember them. Every eg game had pearl, ascent, lotus and sometimes fracture. Also, the map pool changed right after champs so demon1 is also at fault for not being able to adapt. The meta also favored single duelist and cypher was at it's peak with sunset as well so double duelist was out of the question. Also, Jett got nerfed after champs.
EDG had the easiest run after champs. They farmed their own shit region, beat liquid (mid team carried by nAts). Fluked against G2 and then got folded.
