I would put them at high B tier, they are clearly better than a lot of teams in CN, and now I think they would be top 5 pacific teams (If they are in the region) and could potentially make top 4 lan if they dont choke (Not coping spitting facts)
TE international record (excluding Gwangju because they played with a stand-in + excluding CN teams because that's technically not international):
2-1 vs. VIT
2-1 vs. LEV
0-2 vs. DRX
0-2 vs. RRQ
2-0 vs. GEN
1-2 vs. DFM
2-0 vs. DRX
Total:
4-3 record (~57% winrate)
9-8 in maps (~53% winrate)
That's pretty good tbh. Not amazing, but still good. They definitely have what it takes to go deep in internationals, though... their biggest weakness was a tendency to choke in playoffs (both domestically and internationally) but they seem to have gotten past that
