Riot need to release soon If they don't want this copied-version become much bigger (like Mobile Legends and Wildrift) that even original version can't compete with copied-version
That's very popular strategy, make mobile ripoff version first, gain marketshare/playerbase and then dominate the whole market. Like Moontoon did with Mobile Legends. Neteast have so much money to pay for the lawsuits (If Riot sue them)
