Reduce Effectiveness of Boss Movement on the Player

The title is as ridiculous as the scenario that inspired me to write this up.

I was fighting Zicoatl, boss has 10% life left. He does laser with all the additional small lasers from the walls facing upper left corner while I am in melee range to the left side of the boss. The boss turns which TELEPORTS my character to the right of it where six lasers are intersecting and I die.

I'm not playing HC so my initial reaction is "haha, I can't believe GGG left an interaction this stupid in the game" but then I thought about playing Hardcore and losing my character to an unreactable enemy action.

Not sure what else to say beside I hope boss movement isn't going to be something to be concerned about for melee players all the time. I get a boss charging at you should push the player if the boss is a larger size but does a melee player just completely disengage every time a boss is facing away from them/doing a persistent, random pattern attack?
