Why am I having so much lag lately?

[Mystiq]

Your router/ISP. Pressure them to fix whatever is wrong, show them the game. Explain how it measures latency. They'll try to blame it on the game, but it isn't the game.

The problem is your router/ISP.

It is not STS's fault, considering I am playing just fine.

You should look at AL's forums. The bugs section. There's a thread on lagg recently and about 99% of them are blaming it on STS (im the 1% who tried to talk some sense into them). They just wouldn't listen, and I said probably the exact same thing to them as you said.
