As a free to play game, League of Legends is pretty reasonable with its microtransactions. If you do spend money in the game, then you’re probably buying RP (Riot Points) to spend it on optional add-ons like new champion skins or IP boosts (IP is the currency you earn from playing the game, you can spend it on new characters). The important word there is ‘optional’ and no one’s really losing out by not handing over money and League of Legends isn’t pay-to-win either.
The problem with RP is that you can’t buy it in an amount of your choosing, you have to buy it in bulk at a fixed price (though there are different price points for this). European League of Legends players are about to get an annoying shock then as Riot Games (League‘s developer) has just announced plans to increase RP prices by a massive 10%.
