Would this save the future!

Aren't you contradicting yourself? Reaction time first, then anticipation.
What the OP offers is no different than knowing the fight by heart and *anticipate* because you already know what's coming. It simply gets rid of the "learning by heart" phase, by giving you a warning.
Doesn't mean I'd like to see this specific feature ingame, though.

2.1 was officially announced to have an increase (of what magnitude, we don't know) in server position checks for endgame dungeons and PVP. It's not a fix, but an emergency bandaid that will hopefully be efficient enough.

I can anticipate that Titan will throw down a Landslide in my face, or in someone else's face. I can anticipate the Weights, but if i don't react when its under me, I'm done.
Knowing is research. Reacting is the challenge.
