Understanding Riot’s autofill changes in League of Legends patch 12.17 and upcoming 12.18 updates
Understanding the Autofill System Update
League of Legends players recently experienced unexpected modifications to the matchmaking system when autofill adjustments intended for future updates prematurely activated during LoL patch 12.17.
A technical glitch caused planned modifications to League’s autofill mechanics to deploy prematurely in ranked queues. Riot Games has additional queue functionality enhancements scheduled for LoL patch 12.18, scheduled for release in late September.
The autofill feature within League of Legends consistently generates player discussion due to its dual nature. While essential for maintaining acceptable queue durations, competitors frequently express frustration when assigned unfamiliar roles during critical ranked matches.
Riot developer ‘Auberaun’ clarified the situation stating, “We have modifications to autofill safeguards scheduled for implementation in patch 12.18. The current partial deployment represents an unintended early activation due to technical issues.”
Impact on Different Player Roles
Mid lane and bot lane primary players encounter particular difficulties with autofill assignments, as these popular positions experience significantly higher demand compared to other roles. The player distribution imbalance frequently results in secondary role assignments or complete autofill situations for those specializing in these coveted positions.
Previously, support role enthusiasts enjoyed specialized protection through autofill safeguards, with Riot ensuring priority position access for players who recently completed matches in their preferred role. This protective measure created uneven distribution across different player specializations.
The landscape shifted when League competitors observed autofill protection disappearing for support specialists during LoL patch 12.17—without official documentation in patch notes. Riot verified this represented a legitimate modification that deployed prematurely because of technical issues, with additional enhancements arriving in LoL patch 12.18 during September.
Despite player dissatisfaction with these adjustments, Auberaun emphasized that autofill remains an essential ranked experience component for maintaining reasonable waiting periods. The forthcoming changes encompass broader system improvements beyond current visible modifications.
Strategic Adaptations and Best Practices
“Autofill must remain operational to sustain reasonable queue durations. We’ve implemented recent backend enhancements to team role balance and have scheduled work addressing lobby hostage situations that I anticipate discussing publicly soon,” Auberaun explained.
To navigate these changes effectively, consider developing proficiency in at least two different roles. Mid lane mains should practice jungle or top lane fundamentals, while bot lane specialists might benefit from learning support mechanics. This flexibility reduces the negative impact when autofill occurs.
Communication becomes crucial during champion selection when autofilled. Immediately informing teammates about your role preference and comfort level allows for potential swaps and sets appropriate expectations. Utilize the pre-game lobby to discuss strategic adaptations rather than complaining about the assignment.
Monitor queue times carefully—if wait times extend beyond 3-4 minutes, consider requeuing or switching to your secondary role preference to potentially avoid autofill assignments while still maintaining reasonable waiting periods.

Riot previously attempted autofill adjustments earlier this season, directing teams toward “autofill parity” by guaranteeing equivalent numbers of filled players on each side.
Regarding specific contents of the LoL patch 12.18 autofill update? Detailed information remains unavailable, but prepare for an altered ranked environment as you complete your Season 12 progression journey.
The upcoming patch 12.18 changes will likely focus on refining the balance between queue times and role satisfaction. Players should anticipate continued adjustments to how autofill protection applies across different roles and potentially new mechanisms for role swapping during champion selection.
As Season 12 approaches conclusion, these autofill modifications represent Riot’s ongoing effort to improve competitive integrity while addressing player concerns about matchmaking quality and waiting times.
