It seems that the developers want to offer another option for communication.
Recently, dataminer SkinSpotlights drew the community's attention to Riot Games' possible plans. Judging by his find, the company plans to add a full-fledged voice chat to League of Legends 17 years after its release.
In the code, SkinSpotlights highlighted the characteristic line «VOICE COMMS ABUSE» — this is a new type of complaint about voice chat.
In addition, SkinSpotlights was able to find different types of voice chat: group and team.
It is not yet clear when the League of Legends developers may launch such a voice chat.
