Exactly. In the current state of the game, for me, I have to move BEFORE circles or attacks appear in order to dodge, due to latency, bad servers or whatever (say all you want it's on my end lol, I know it's not. I have a tons of online games on my PC this is the only game I have to do this).
If attacks were to be randomized they would have to be super easy and boring in order to allow players like me to dodge.
If latency is fixed, sure. But as long as it's not, don't see that happening, game is just not build for that.
Edit- FATE bosses are randomised, are they not? lol
