Southeast Asian League of Legends players have been playing the game under the hosting of Garena, and have not been keeping up with the rest of the world due to that, so Riot are giving out rewards to those who complete the transition.
Garena have not been doing their job all that well in recent years, it would seem, as the players have been playing the game on high ping on other servers, than their own, hosted by Garena.
So, Riot Games are taking back their game in Southeast Asia, and are giving an immense gift to the new/old League of Legends players, joining the rest of the worldwide community.
Aside from the various capsules, other similar rewards these players will be able to get, the most important one, it would seem, is that SEA players will be able to get all League of Legends champions for free, who were released from the game's launch until 2021.
This is a number of around 150 champions, who will be unlockable through the usual missions, 157 to be exact, with only this year's five champions having to be bought the usual way.
In addition, the SEA players will also finally have access to things we have all been taking for granted, such as pick em', Steam Drops, and even Clash tournaments, which Garena have not organized, ever!
