Simply put for the last two patches both Skype and Discord have caused heavy lag in game when in use. Prior to 7.8 there was no negative interaction for using both Skype/Discord and League at the same time.
Yes, I realize that it could very easily be either of the program separately. It could be a problem with my internet connection, or with my computer itself. It does seem slightly odd that both change in the exact same way at the exact same time thou. -- I'm posting here with the hope that someone else has had the same problem and fixed it, or it's an issue that Riot could respond to with any information at all, it'd help greatly.
Thank you for your time-
