So i think ilve figured out somewhat the problem is, the later the video goes on, the more delayed the audio track gets from the video channel, i have too much editing to redo ALL of the tracks but i have like 6 different audio tracks that i could try to fix, if any one knows how to fix PLEASE let me know! 
Are your League of Legends source files variable framerate? Have you converted them to Edit-Friendly? I do not have experience with variable framerate videos myself but I keep hearing that they can cause problems…
