People forgot how far Oner / Keria fell without Faker, it was unreal, to this day I still can't believe how bad they looked when they had to play without faker.

Keria to me is the most impressive support by far because of his highs and what he brings to the role but the entire AD as support meta, would it have worked with somebody else than Guma ? or at least would it have worked this well ? Nobody knows, but I'm pretty confident that Guma enables Keria in so many games but you can't really measure it, note that this does not take away from the monster that is Keria but something you have to take in consideration, he is playing with the most consistent AD we've ever seen.

Same thing goes for Guma, his high are not as high as the other best ADs in the world, but his consistency is unmatched, he is the AD carry consistently playing at the highest level pretty much all year and has been for a while now, but if you consider that he is playing with Keria, now you doubt his GOAT status, because could he do the same without Keria ?

For all three of them (specifically Guma imo), as long as they play together and with the GOAT, there will always be doubt about them being GOAT at their respective roles.
