Oh my fricking god why has no MMO ever done this??? Random locked affinities

I just thought of this. Why isn't there any mmo where your magic or class affinity is locked at character creation? Like an Isekai but an mmo. Imagine this, anti cheat is made somehow so you can only make ONE account and everything is random. No rerolls, ip switching doesn't work, etc. You have like 15 magic types or something and some are more random than others. Some people even get 2 but each are slightly weaker to compensate and combine like a naruto kekkei genkai. You might be born with the rare dark type affinity or wind and water so you get special ice abilities from having both. That would so fricking cool. Each would be useful but the gimmick is just like real life. You can be born a handsome guy with shit magic and great at stealing or an ugly guy with a tri magic affinity to create storms. Idk I just like the idea. Call it Magic Lock or something.
