what 100 factors lined up for them? They had one of the hardest roads towards a trophy you could've had in Bangkok. Really only their match against Trace wasn't as difficult as it could've been, and even then it was not an easy game. Facing the favourites for that tournament, Vitality/EDG/G2 (and 2 of those multiple times) and still winning the trophy. EG in 2023 champs never faced fnatic, who probably would've given them a much harder time. (Not delegitimising EG's win, just pointing out how they could've had a harder run)
T1 are trying different things now, they need to find a groove for single duelist, because they excelled at double duelist. Trying out things will generally make you worse, less reps, not as strong instincts etc.
