Agreed with the more you do the fights the more you get used to them and expect whats coming in addition, and classic movement will help you for more then 1 reason.
Dodging in straight lines is your enemy you need to curve or "staple"
Once you are out use something so it knows your out if you can
Don't attack on your way out
Why below, you can stop reading if you don't care why.
The game does not use true positioning, it predicts where you are at based on its last 3 good sample points which have various triggers and a 4th point that it assumes you will be in. These are automatically every .22 seconds when you are in a static position or moving linearly. So if you do not just a technique to create more of these points once you are out then you need to be out for almost a full second to be out server side. Other triggers are when initiating an ability, completing an ability (same info as initiating in this case), when it receives erratic control inputs (non-linear) these are sampled ever .03 seconds once detected by the server. Once it receives a new point it corrects your position as seen on the server.
Ensuring you remove the position checks inside the aoe should be your objective once out.
Curving during the whole dodge the server is constantly updating your position every .3 after the initial .66 seconds it takes the server to recognize non-linear movement across the entire dodge. This isn't always possible when you are trying to clear larger circular aoes (wotl)
Stapling at the end, of a dodge forces the server to pick up additional positional checks outside of the aoe. In this case you are already laying down a line of checks so the last on on the staple takes .28 seconds to lay your 3 down outside the aoe as opposed to the .66 once you are out if you continue to run or just stop in place.
Using an ability lays down 3 checks at the same time in the case of instant use abilities, the server will predict your position is static because the only checks it has to work with are in one spot the pick up time is .22 seconds if you are out. The problem is if you use an ability while you are still in it takes its 3 check from the position you used the ability in. This makes the server predict your movement and thus position as slower from that point to the remainder of your dodge.Assuming you are barely making it out on your screen before said aoe goes off the server still registers you as inside it based on its prediction model.
