Day 4 of EB just started,
Another new box event just started
An ILTQ just started

And the servers are crawling. It's taking me and many of my guild mates more than 2 minutes for our avatar to stop dancing around for every free hit.
One of my toons killed a boss with 5 hits and it took so long that he had half a health bar left.

This is happening around the world in many countries.

This happens every time a new event starts. This is the worst it's been.

By the way, good luck killing the 15 minute EB on 3/10 Legendary with 20 hits.
