Not anyone that bought enigma day 1 can have several if not dozens of Speedrun World Records.
You are biased because of this whole 99 race that was indeed rigged,
But it doesnt make him suck at the game just for that.
Now I watched his stream like 10min during the race and saw him blatantly idling in town while Telesorc was TPing to Baal and I find that to be low grade, but I can not not acknowdledge his achievements on the Speedrun side of the game.
I think it’s a bit of both.
I would argue the groups who do playthroughs in 2.5hrs have skill. Not every group can do that.
But once someone buys their enigma 16hrs into a ladder reset or whatever the main “skill” becomes how much of a masochist are you and how little sleep are you willing to endure.
Generally the race to 99 has both, but part B (how little sleep are you willing to endure) is going to be the far bigger part of the equation.
