I know 'curiosity killed the cat'...but I've been wondering something and hope I can get an answer from staff.

What is the reasoning for blood control being banned? I can understand control over the blood of others...but what about Self Blood Control? Why is that banned? I'm just curious and don't really expect an answer o.o

Most notably, blood control isnt limited to just your body, regardless if you say only you can control your blood. If your blood mixes with another's, their blood becomes your blood. Even if you specifically said that couldnt happen; you would literally kill yourself in a matter of minutes due to blood loss. Its just not a good ability in general if its not OP as hell

Ok I was just wondering cause I have a fullbringer with this ability, and I can say she isn't OP and is fairly balanced, if not a little more negative on herself. I can link her app if you would like.
