This is exactly the stuff I’m talking about lol. You’re telling someone who heals about damage patterns and what’s punishing. Look at halls of infusion… the first section with the orbs, if expulse gets off in a 20+ Fort key it’s over… if people stand there and tank the fixates in brackenhide they die… if people don’t interrupt cyclone in vortex and you get CCD as a healer it’s over… if people don’t stun the maggots in underrot and get frontal’d they die… withering curse, or the worms in underrot can easily cause wipes… people not stunning falling stone casts in uldaman… not interrupting chain lightning or basilisk thorns… LOSing the thundering clap on the golems… moving out of sea spout in freehold, or interrupting thundering squalls… not moving from avalanche in nelths lair, or standing there getting blasted by pelters not using defensives… not killing the maggot before it transforms into the worm… not using chains properly in neltharus… the list goes on and on and that’s not even including the bosses which have massive potential for errors by people.
Obviously in low keys these can be healed through… but in 20+ there’s already absurd amounts of unavoidable damage that if players are getting hit by avoidable stuff on top of it, or not interrupting/stunning mechanics it very easily leads to wipes
