zellsis & xeppaa's lack of discipline will be the reason why they never win anything internationally
Zellsis and Xeppaa aren't undisciplined, that's just their branding
if you watch any behind the scenes content of C9 you will see that they both take the game extremely seriously, especially their roles in helping Jakee and Runi adapt to the big leagues
plus big daddy mCE will shut down any rowdiness
They lost so many man advantage situations. funnily enough they troll a lot in their ranked streams too so that habit is creeping up in their pro play. While s0m rarely trolls comparably, he tries to win the round even during 1v2 or 1v3 rounds which helps him in clutch situations. They could've 2-0'd NRG but they threw so many post plants by over peeking thinking they were better & crashies put them down like a dog.
