you didn't say face of teams which got me confused, you just listed a few names but that's ok.
100t-asuna
sen-zekken
g2-not sure(Trent, valyn(they don't have a main duelist)) jawgemo when he goes
eg-jawgemo currently
lev-aspas currently
kru-keznit
c9-oxy
nrg-s0m(he started off as duelist which really set him up for popularity, mains duelist in ranked which just boosts his popularity because he frags out)
furia-mwzera-flexs but also plays duelist
mibr-no clue
heretics-benjyfishy(mostly because of Fortnite)
fut-cned
fnatic-boaster
vitality-not sure don't watch emea a lot. I just know sayf that's pretty much it. runner ig can be too
navi-angel
I'm too lazy to go through all the teams but most of them are duelists whether you like it or not. the ones that aren't duelist, like fnatic is because of something else(personality) or doesn't have a duelist currently(loud, g2-jawgemo would be the face of g2)
and like team liquid, they are just bringing in new players to the scene, who have never played t1 so yeah nats makes sense. but if scream was still on tl, he would be the face of tl.
