Patchwerk - nope
Grobbulus - nope
Gluth - nope (even if someone griefs drags zombies to Gluth, it will not cause a wipe, just prolong the encounter)
Thaddius - nope (stupid people just die here, you only run into issues if a sizeable portion of your raid cannot handle the polarities)
Anub'rekhan - nope
Faerlina - nope
Maexxna - nope
Noth - nope
Heigan - nope
Loatheb - nope
Gothik - nope
4 HM - nope
Sapphiron - nope
KT - nope (worst thing that can happen, Melee camps chain Frostblast and die, but that also just prolongs the encounter, not instantly wipe you)
Sartharion - nope (unless your tanks decided to turn the boss towards the raid while the breathes - but that's a low bar considering that could also happen on virtually any dragon boss in Classic)
Malygos - see above
It is frankly unlikely that the mistake of one person can spiral into a wipe in T7.
