Yeah, but it's something we absolutely ought to be handling in most fights. Or a variant of it, it's not like other games have no long explored the space of "consistent raid damage output":
* A simple DoT ticking away constantly.
* Random attacks hitting 1-3 random people for a non-trivial amount of damage every few seconds (so they need targetted healing lest the next such attack or overall AoE could down them).
* Similarly, random circle of line AoEs that have no prior warning that hit for a lower but still significant amount, these would force the group to spread apart in idle times plus assuming they would not stop during mechanics they'd add some extra spice onto otherwise fully dependable situations (their damage is of course much lower than the single hits).
* 360° cleaves where AAs hit everyone but the primary target in melee range, too, but for far less damage. Basically melee DPS need constant healing attention.
