He can be the most intelligent participant but the most incompetent game manager. They aren't mutually exclusive. I am not saying he definitely is incompetent, but my impression from WOW Classic TBC Gold the interviews he did is that he don't understand what the players want or he's always in a situation where he's at the stage of no return and wind up doubling down and defending the game designs.
When you're a healer doing less complete healing than your tanks in raid you have fucked up, the guy lives in a bubble and has no idea what the sport is like for the average or even top end player because he himself doesn't bother. He grey parses in raid, and runs 1-3 mythic plus dungeons per week even early on in spots while his guild funnels him gear probably.
He absolutely lives in a bubble, and now I am convinced he can not understand as many cannot who live in these bubbles but the guy is quite intelligent, it just does not apply to his current job .
Once upon a time that his guilds site was THE place for understanding what goes on under the hood of this game, and that was spear headed by Ion himself and we thought we wanted someone like him to buy WOW TBC Gold take ghostcrawlers chair in the table... However, it turns out that just because you are really knowledgeable about something doesn't mean you should be in charge of it.
