Ranked Play

Why am I getting 1-5 LP for a win, but losing way more for a loss?

I won a game but lost LP / I lost a game but still gained LP

Leaver Issues / Disconnects / Bad Players

I got a BugSplat Error
1. BugSplat is Riot’s critical and compatibility error reporting tool. It’s used to identify game conflicts with your specific system.
2. Unfortunately, this means that these issues happen on a case-by-case basis and it’s hard to offer a fix on the forums.
3. Some basic things to try include taking a look at this article in the KB, updating your DirectX, Video Card Drivers, Microsoft Dot NET Frameworks, Windows Updates, Reinstalling LoL
4. As mentioned, because these issues are system specific they are difficult to address on the forums. If you need additional help please make sure you submit your BugSplat report, follow up with a ticket to Riot Support and include your DxDiag report.

I have a leave, but it wasn’t on purpose
1. The leave system was always intended to flag disconnects for any reason. Even if you didn’t rage quit, you still get a leave.
2. If you acquired a leaver mark due to circumstances beyond your control, (including disconnections, game crashes, etc.) unfortunately it is not possible to remove leaver marks from individual player accounts.

I was banned what do I do?
1. There are several types of bans ranging from temporary suspensions to permanent account bans, you should automatically receive an e-mail with ban information and terms if this occurs.
2. If you want to find out more or feel you have been unjustly banned, please open a ticket at
