does SEN still have pot. to qual 4 LAN?

considering how little they actually practice, how can we assess their skill together as a team if they don't show much progress in qualifiers??

no

I'd say so, their matches were very close ignoring optic.

N😂

in another world where there are more slots, maybe. but NA only has 1 slot in LCQ and there is no way they are close to top 3 of the teams in LCQ

Nope

all of their players have proven that they can be top players in the world (other than kanpeki).

if they understand the meta, adapt it, and practice, i can see them being good
