The answer is “yes but let’s act like it’s not doomed” :

Ultimately, while NA League has lost much of what once allowed it to attract such a sizable following, the LTA North still has the same core as the LCS. The dissatisfaction that the rebranding received is understandable and doesn’t seem to be letting up, but things may settle down as fans and teams further adapt to the changes. With teams like FlyQuest and Cloud9 leading the way, the region should continue to make waves internationally.

The inclusion of South American League in the LTA also means that the potential viewer base is even larger, further highlighting the possibilities that do exist for the LTA. But ultimately, it all depends on whether Riot actually listens to its fans and continues to make meaningful improvements over time with the long-term health of North American League of Legends in mind.
