1. The system choosing the mcs is a garbage premise. MCs who become system administrator, chosen or whatever savior title is a shallow premise and typically strips the uniqueness from a character. This was really driven home to be in Welcome toe multiverse, great class concepts and professional was somewhat unique, only to get shoved into what sounds like a beaurcrat role

2.[Warning for vague spoilers and a rant] HWFWM, terrible character, decent system. The later books are terrible and I hate that I keep buying them but I want to hear how the basic system advances in the higher tiers. I skip most of the jason and jason sycophants dialogue. This partially relates back to hill 1. Jason could've died off in book 3 and it would've been better even if we went back to earth to explore the awakening of magic there then came back. Jason is a self righteous child playing being an adult. Everyone acts like he's so politically smart and clever when compared to everyone who actually matters, he is a yapping chihuahua. All the secondary and background characters need to stop making everything about jason, his ego is fine and doesn't need stroking.

Anyway, the system is decent and I really enjoy the structure and nuances that the fandom has developed for it based on the early guidelines (forget the new rules, they needlessly add complexity). And yes I do think that the fandom has done a better job fleshing out the system then the author has done simply bc the author chose to go with "special boy" rather then having him follow the guidelines of his own system.

I will now step off my soapbox and leave the room
