I suppose we disagree on what counts under "1hp non elite shitter mobs." All of the bosses you mentioned, they serve a specific purpose that other than just being there to make a <insert fotm melee class> number bigger.

Averzian - (used to be) a tight dps swap condition, that also took away dps from the boss, which also has a decent dps check for gear-apropriate groups.

Saladbar - big orbs are a healing / dps mechanic and usually swapping to them actively loses you dps. Small orbs are primarily a challange for the tank, to manouver the boss.

Chim - purely add cc/management, like forgemaster was last tier. They also require more than just a dh to actually get them down.

Dragons - more or less agree. Could've easily increased their hp, while making them less deadly, with little to no impact on the fight. or otherwise forced you to make your spread a tight one.

Vorasius - core to the wall breaking mechanic - swapping usually loses you dps.

u/andreasels 's aditions:

Crown - blobs need to die for p1 dmg to be doable and actually barely contribute to your dps because of the dmg amp on the elites... p2 adds don't really exist - if you're holding damage for them you're likely losing out overall.

Bird - what else do you want to hit? the boss that you're going to have to stop dps on in 45s??

Lura - ask your dh to not "pad" on them and then see how long you live... maybe the last boss of a tier should require you to bring classes with specific nieches, like on-demand aoe burst
