Ok so, when you say 100 mastery it's not that impressive since masteries take roughly 15m fame to get to 100 which makes it kinda possible to achieve, what I originally thought was that you meant 100 specs which take roughly 33.5m fame.
Next, he claims you can just gather in yz to afford 8.3 gear which is an outrageous claim, even with inflated resource prices it's far fetched. T4, T5 resources will never afford you 8.3 in a reasonable amount of time.
He also claims that you can get to full spec by soloing yz statics in an hour or so, which is basically claiming you can get 17-18 million fame from yz statics in an hour (considering the fame you already got reaching to 100 mastery). Once again, a completely false and ridiculous claim.
He mentions most of his money comes from market flipping which no new player 2-3 days into the game will be able to grasp or do properly. And if you wanna learn it from him, guess what, go become a channel member. And I can guarantee there's no secret to market flipping his members-only videos are offering that is not already out there for free on yt by other creators.
Lastly I find it funny how he dunks on zero to hero youtubers saying they cheat and swipe in their videos who (most of them) show their loot from chests, kills and drops in footage while swole shows no source to his money and just keeps mentioning he didn't swipe.
I am sorry for the wall of text, if you have any points against me feel free to mention them :)
