Hi,
Recently my league of legends ping has been hovering around 60+ms when it used to be around low-mid 40ms. I contacted Riot games support and submitted various tracert and WinMTR reports and they said to contact my ISP as it was a networking issue.
I have a VPN, just a regular one not specifically for gaming, and setting the server to Chicago (where the League of Legends servers are located) and playing through VPN brings my ping back down to mid 40ms.
There seems to be some sort of issue with Shaw routing for this traffic.
Below is the results of a WinMTR test with and without the VPN (first being with VPN, second being without)
