I’ll say if you think a geared 80 can out DPS a geared lvl 11 twink, you are either clueless or need to share the drugs you’re on.
(Case in point, my lvl 11 twink usually does 90% or more of the entire party’s DPS, one time a Paladin was actually doing about 50% of my DPS… i was shocked he was putting out that much damage, i inspected him and this Paladin was head to toe full mythic raid gear… he was obviously skilled to be in full Mythic raid gear, he was trying to out DPS me, and did about 50% of what i was doing).
