Besides banning bots, the next best thing would be OCE servers. Before Lost Arks release a majority of the OCE community designated Valtan as the primary server for OCE players and Mari as the back up.
Valtan and Mari are without a doubt the servers that experience the most trouble and considering SA has a much smaller playerbase it’s hard to understand why OCE with a much larger player base doesn’t have servers. I think it would be a fair estimate to say there are about 15k-20k players from OCE/SEA on NA West
