Your lack of support staff is what's going to make me look for a new game
Here's my timeline with support:
Input ticket about a day and a half ago, explaining that I can't log into the game, and what I've tried.
12 hours later, canned response from Riot explaining to do the exact things I've already done, asking for logs, I've already provided.
Re-explained what i've done, and even told support that I can log into other regions just fine.
6 hours after their first response, disregards what IS working and provides yet another canned response.
I fully responded 5 minutes later with even more updated logs and again, what IS working
12+ hours later, still no response.
You should never assign a single person to a ticket if they're not going to resolve it or escalate it within a timely manner.
