The beta only started to roll out now. The USA, Canada and some places Europe are covered, but others will need to wait until they get to have their own servers, and Riot will not deploy servers in regions where COVID 19 is still a risk or where lockdowns are in place. I guess Asia will be next, then South America, and only then we will be considered.
I believe the game is worth the hype. I watched Summit play yesterday, and he likes it. Shroud likes it so much that he started making tutorial videos on the game. However, the insane viewership numbers, and even though there is lockdown in place and beta key drops, seems to be manipulated. They already admitted to viewbotting and many people idle the Twitch streams to get key drops.
Some people are selling beta keys @ $150 at the moment. Apparently Riot is trying to get it under control.
