You people are nuts. Nathanos never 1 shot people. His adds were the reason why people feared him. You could kill him with a raid of like 15 60’s.
Not only did they bring 2 full raids of 40’s, but they cheesed him using hunters. You didn’t have streamers that could organize cheese like this in Vanilla.
Streamers are going to be able to cheese a lot of mechanics because people weren’t as organized and had armies following them around.
Even in WoD my level 19 twink could kill level 90 npcs. Even some elites. It took a long time. But she could do it. Mixed levels fighting eachother was around for a long time.
As for Nathanos in World PVE hunters can do almost anything. If a mob didn’t leash a skilled hunter could kite a mob and slowly kill it from one side of the continent to the other.
Also, isn’t it that he spawns skeletons with every heal? Like even healing ticks from a hot should cause a skeleton to spawn. If the strat was to no heals and just kite, and everyone in raid was experienced, there probably weren’t many skeletons.
Finally, did they kite him and his hounds over large area? Maybe they should have put a tigher leash on them, that would defeat the strat.
