Can we please, have a modernization for the servers. (Specifically, tick/refreshrate)

You can do a quick imperfect test to see how bad it is by playing the game side by side with two computers or clients.

Yep, there's a youtube video that shows the player doing this: https://www.youtube.com/watch?v=hToWKu79Jm0

One characters jump animation on one computer is already complete by the time the 2nd computer even sees that character start its jump animation.

And to think, this game used to be quite a bit worse. Back around ARR or Heavensward maybe, when people were still running the Titans a lot, I remember having this issue very bad. I would run out of a Titan hit, see someone behind me, I am out of the red bad, they are in it, yet I get hit and they don't. I remember around this time they did a pass that did improve this so I largely never see this anymore. However, sometimes I can get the slide casting, be just in the line inside or out of a bad red and get hit or not.

YES! When ARR first came out, Titan EX and Twintania used to be horrendous.

I remember this. SE actually had to increase the server update rate so players could complete these trials. Before the servers were updated you could be out of the AOE for around two seconds and still get knocked off the platform.
