This isn't a worst of list, this is a expectations vs results list.
Gimme your own cause I'm curious but mine are.
5 Vitality (one of the more underrated teams going into this year, but hasn't really met expectations yet)
4 Loud (will excuse first game cause Riot fucked them over, but haven't looked like their normally dominant selves this stage, pulled it back slightly at the end though)
3 JDG (sucks seeing such a good roster in former Rare Atom, turn to shit)
2 Sentinels (from masters winners, to missing out on playoffs)
1 NRG (do i need to say much)
honorable mentions: T1, Zeta, Wolves, BLG
