Off topic somewhat.
Lets say C9/CLG/TSM and IMT are in a LCS format best of 3. Competing with the NA won't be the top 3 LCK teams but the 4th-5th-6th and 7th next best LCK teams. SO No SKT, ROX or KT Rolster. So representing the LCK in no order from best to worse vice versa Jin Air/ Afreeca/Samsung/ESC.
IMT can't win in NA let alone against LCK teams involved. Reignover and Huni are great no doubt but let's not forget that Reignover was called Reignover because he was first in the LCK and which ever team he was on it was OVER for them hint the name. While the Top and Jng is the strong point for IMT their Mid/and bot compared SUCKS. Bang/Pray/ and other LCK teams have shown that it takes more than just NA wanna be Faker Jr's to win games.
TSM BJergsen hands down the best NA mid EVER sometimes called the Western Faker( in NA).
TSM beat SSG in groups in their first game what did they do since ? What did C9 do ?
JIN Air is this team slow you better believe it each split they are around the 45 min per game it seems. Their however taking games off SKT/SSW/KT year after year/ split after split and are constantly 5-6th in the standings each split (against the top teams not just the mid tier LCK teams)
TSM 2015 summer was close to Jin Air as TSM was around the 39-42 mins per game and they had a hard enough time just trying to beat TDK and TL in NA. TSM goes to Worlds that same year and not only would they get small leads they would be up in kills, other than 1 game that they won they lost 5 to be 1-5.
Afreeca and ESC have shown that not only can they compete with TSM in 1 international stage if I can remember it was in DEC I think but they can take 3-4 games off TSM which at the time was the best maybe second best NA team. Given 1-2 more splits in the LCK and these two teams will be the next teams to represent the LCK. Afreeca have shown that they can go toe 2 toe with SKT as SKT would lose to Afreeca multiple times. Can NA say the same ?
Season 3 Worlds SKT-TSM 2-0
IEM SKT-CLG 1-0 SKT-TSM 2-0
MSI 2016 SKT-CLG 4-1
Season 6 Worlds SKT-C9 2-0
1 win maybe 2 somewhere in the past 6 years against SKT
^^^^^^^^^^^^^^^^^^^^^^^^^ This is just NA vs one of the best if not the best LOL team EVER. NA's record against other LCK teams that would be good for 1 year or split before splitting up(SSW) or are a LCK challenger team(ESC) isn't really that impressive.
Overall NA wouldn't really do much against the "mid tier LCK teams"
Would NA get a few wins here and there? YES
Would the outcome be any different other than LCK wins? NO
