The magical experience of isekai!?

so I've been into rising of the shield hero for a while now... a lot of things about it ALWAYS bugged me starting with the fact that the world functions like a game and the heroes are supposed to fight together in a party.... BUT WHERE'S THE ARCHMAGE?! THE BLATANT DISRESPECT TO THE MAGE CLASS IS REAL AND ANGERING! so I decided as a gamer who rather enjoys being a mage and healer, I'd rectify that. and other things. for all intents and purposes this is a self insert but I will be using my proxy OC that I use in my nutty fangirl daydreams. DON'T WORRY! I'M NERFING MY PROXY! this will follow the plot of the anime because..... I want to. and I'm..... LAZY~! and using the manga is too much trouble and the light novel is 800+ chapters long. So FUCK THAT! anyways if you read this and think it's lackluster then I want to see you try your hand at writing tate no yuusha fics! no that's not a challenge or insult it's just a desperate plea for more tate fics... we need some more variety! Alright I'm gonna be honest here. This story is laughably bad. So read at your own risk. The only reason I'm not revising it is because 1 I'm Lazy as fuck and 2 to serve as a lesson on what NOT to do for new writers. So like I said, read at your own risk.
