MK4 is to hard

[Packetdancer]

A general reason why a lot of people struggle with XIV's content is that they're waiting way too long to move for mechanics.

With very few exceptions it's safe to run into something as soon as you see the animation happening and the mentioned laser mechanic is a perfect example of one that gives you little to no time to dodge it if you're not abusing the damage snapshots to the fullest and not switching sides the instant you see a beam go off.

I'm going to just underline this and then run over it with a yellow highlighter for emphasis. For any mechanic that involves dodging between two spots in this game, I do not think there is anything more important to remember than this.

we beat it ... I have a heart felt appreciation for this forum, thank you

Glad you got through the fight! And glad the help/advice was useful.
