edg is better in a lot of things:
outaiming ppl: just find clips on youtube
strats: invented a new lotus comp with double ball smokes to counter the current meta. it is smart in two ways as clove can solo hold C long with the oneway and can always fall back and put the entry smoke. double smokes also hard counters the current meta as there was no flashes except omen flash, so you would have a hard time finalizing hitting a site.
nobody's mid round calls were also good, for example in a game of sunset against TH, TH called a timeout. they read their intention to reclear B main with 3 people as they were ecoing, so nobody instantly called a rotate A through mid, catching the mid and A site player, leaving a 5v3 retake.
mentality: most games they lost the 1st map, but they could always come back the other 2 maps. even in finals when kangkang aced and still lost the map, he was still cheering his teammates up. when the team was losing 5 rounds in a row, it was kangkang who stood out and eco 4k'd TH with a guardian.
with all these i cant see the reason they shouldnt win a champion
