I am just suggesting what works for me. I been using the paid version of ExitLag for awhile now, and it helps with my lag issue especially I am from Singapore so the lag I got usually is unplayable for me. You can try it for 3 days if you like it you can continue to use it and if you don't you can just leave it.

I had lag issue with L2 too but it seems like ExitLag had fix my issue. You can use their 3 days free trial and see if it helps. https://www.exitlag.com/en/
