We know from pro players G2 was beating every team apart from Damwon in scrims by the end of last years worlds, there is a reason players like Doinb and Rookie said they were perhaps the only team that could beat Damwon (though I think they underrated Suning at worlds). For the past 4 international tournaments they have either been knocked out by the champion at any given point or they have won.
Caps was the 3rd best mid at worlds after Showmaker and Angel (Knight and Chovy were definitively worse, BDD, well we saw)
Rekkles was top 2 at worlds with Huanfeng.
Mikyx was top 4 at worst, after Beryl, Keria and Lvmao.
Besides last years meta didn't even suit them, and as always European teams need at leasy about 4 weeks to get close to their peak, because it is true that competition there is worse, specifically the mechanical level of soloq.
It’s moronic to put them lower than the top 5, the only LCK team you van put above them is Damwon, and you can put EDG, RNG and that's it wbove them, because we literally know they wete better than these lineups of TES and JDG.
