@Minezuki but again, it doesn't try to be realistic. You know nothing about the others skills or what are the stats of the other characters.
And about OSO, talk about Toaru no Ossan. It's basically the same system. (In fact, at the start, Toaru no Ossan was OSO but in better)
And why I hate OSO: "Enchanting is dumb because it has short range and mage aren't frontliners" says the GODDAMN WARRIOR/LIGHT MAGE.
Archery is useless except if you pick alchemy, that the MC has strangely enough.
Enchanting is not worth a lot except if you have far sight, that the MC has against all odds.
Don't tell me that on the millions of players, none evolved enchanting to unlock enchanting items which are totally OP, everybody says it.
First Earth magic: explosion... Why? You could put rock throw, stalagmite launch, or anything, but you choose the spell that 90% of the time would be a fire spell. Also "Earth Magic is the worst magic" -> second magic is stone wall. Yep, no backliners ever need a solid wall to protect them.
It's the whole: "let's make skills convenient for the MC while saying they are useless" that irks me. Here too there is that (let's make skills convenient for the MC) but the story never try to make believable. Just the first fight, where she plays with the rabbit gives the tone. If you want to be believable, you need to make the MC use the skills intelligently. You can make some things convenient because it's just a story, but you need to avoid it. (And that's why I like Toaru no ossan. While it's a bit exaggerated, it's by how he use his skills that he wins, not because the skills are cheats).
