Addressing Leechers in Crystal Tower

Drako that would mean most if not all of a raid will be kicked due to doing nothing for certain boss attacks.

Other than the five headed dragon's heat wave attack, what boss in the game has you doing absolutely nothing for an extended period of time?

A lot of bosses have mechanics where melee have to run back and forth, so there's some downtime as they often have long cooldown or low damage/resource for their ranged attacks..if they even reach (ex. running to pads during scylla, hiding behind ice burgs at amon, etc.)
There are several where people get frozen/inactive due to the mechanics (Ice balls at scylla, pools of poop at cerebus, being frozen at amon, etc.)
Several where you have to do big moves away from the boss to handle mechanics where even ranged can't reach (lightning and fire balls at scylla, soaking far away meteors during cloud of darkness, etc.)
If you're melee heavy in the Lab Atomos, you'll have melee standing on the on pad doing nothing.
Immune phases of bosses when no adds up.
Etc.
