Also how about well documented raid boss tactics?
Such as on third phase Onyxia, which you could wall-jump or simply run up at a certain spots on the walls, which yno fire would erupt and the raid takes far less damage.
Or in Molten Core, how about offenses which got guilds banned during vanilla but over the years in Warcraft became the norm? a great example in Molten Core how you can skip every single pack of trash by wall-walking directly to Gehennas… this got guilds during vanilla banned, however since vanilla, trash skipping has become accepted and is normal practice for most raids to skip any and all trash possible…
or how you can mind control the scarshield spellbinders in blackrock spire to gain 75 fire resistance on the entire raid for one hour and take the buff it into molten core.
or how you can tank magmadar from within a wall, avoid all mechanics and just melee him to death.
or in BWL, how an alliance paladin can cast divine intervention on the MC’d razorgore, everyone dies, priest is soulsharded, all the adds despawn, priest rezzes everyone up and proceed to kill razorgore.
or how if a tank got burning adrenaline from the vaelastrasz, priests and whoever else can spam mind vision or whatever spell on the tank to bump it off their debuff slots so they don’t die/explode (and most importantly, lose all the threat they have on the boss).
or kiting and fighting broodlord in vaelastrasz’s room, where the ranged would proceed to attack him from the upper floor, and when the boss woudl aggro to them, the boss would slowly make their way up stairs, which then players just simply jump down off the ledge, laugh, continue attacking the boss, and when the boss made it back downstairs… rinse and repeat…
using stratholme holy water on the nefarian encounter to nuke the adds.
and so many other clever well-documented strategies and clever ways to defeat virtually every raid boss in vanilla…
Dungeons bosses too, such as the final vancleef fight in deadmines, where you can have a ranged dps stand on a cannon, attack the boss’ adds to pull threat off the tank, and those adds will evade as they can’t path to ontop of the cannon… thus leaving the rest of your party to focus on and kill vancleef without any adds to worry about.
All of these are considered unintended, however are imo, clever use of game mechanics or whatever… so wonder if these would be considered bannable offenses if guilds or pugs utilized these tactics to get boss kills or to trivialize certain aspects (i.e. adds) or negate deadly mechanics or breeze through phases of a fight…
