they don't feel confident in doing a "super team" anymore and will use TL structure.
Considering their academy team is stomping it seems like their domestic talent scouting/building system is pretty damn good, would personally love to see TL use that to pack a super promising domestic trio around 2 of the best imports that can find to compliment it. Similar to EG, I think that hybrid system historically works great for NA better than trying to stack a full team of the biggest names you can find that seems to clash against each other more often than not no matter the region.
Obviously doing well at Worlds with a full domestic roster is the dream, but until LCS gets near it's former glory with tons of hype and 500k regular season viewership again, I just don't see that happening soon. If Riot/Jackie can make the game pop off that hard in NA again tho...perhaps we'll see another S4 C9 type roster again.
