Lag spikes since February 2017 (currently June 2017)

The issues i have been dealing with are exactly such as https://forums.verizon.com/t5/Fios-Internet/Lag-spikes-since-Feb-22-2017/td-p/831191
This forum seems to be archived as i cannoy reply to it, but i need to know the solution. The lag spikes have been going on for almost 4 months. Had the verizon box in the house, outside the house, and the router all replaced, changed IP addresses but it is still occuring. I have spoken to many technicians, and verizon agents/supervisors but the issue is persisting still. As the above forum states, i too play League of Legends, and after contacting their support and providing them the info they asked such as WinMTR logs, they concluded that it was on verizon's side, which the supervisor i spoke to said there was not much more they can do as it is "outside of VZ's network". The issue occurs on all devices, wired and wireless, 2.4gz and 5gz. There is just no escape. i have done all i can and now i'm asking if someone who had this issue got it resolved or has an idea how i can fix it.
