A small percentage of League of Legends players have been using an exploit that lets them cast powerful spells one right after another. The exploit let players add more points to the game's Mastery system that would normally be allowed. But LoL developer Riot Games says such tactics are "bull****" and made moves to fix the loophole that made the cheat possible as soon as they heard about it.

Games with ultra-competitive communities are always going to be filled with people who try to find an edge over their opponents. That's okay. What isn't cool is when that edge crosses the line and breaks the balance. In some games, hacks, cheats and exploits go unnoticed and unpatched. Not with League of Legends, though.

In a post on the League of Legends forum, community manager Andrew Beeglesaid the following about the exploit:

That's bull****, and we're not going to allow it. That's bull****, and we're not going to allow it.

We take this seriously. Nothing is more important to us than the sanctity of our game, competitive or otherwise. As soon as we discovered the issue, we immediately dropped everything to find both immediate and permanent fixes. I'm happy to report that the immediate fix has been implemented, and we'll be restarting all regions this evening to add some redundancy which will prevent similar exploits in the future. As we continue to investigate and further analyze data, our primary commitment is identifying players affected and doing everything within our power to make it right.

Is this the end of people trying to ruin your experience? No. But we're committed to stopping this kind of behavior in its tracks, and are discussing ways to increase our monitoring and development as part of that commitment. We have comprehensive logs and data that allow us to see precisely who did what, and also who was negatively affected by this malicious behavior. We've identified all of the players that have been using this exploit, and we're going to be taking firm action against their accounts.
