Okay I get it, you can't be too over powered, but why is it that pretty much all fan semblances I've seen seem to have some downside to them that makes them pretty much useless? "So and so character can't use this semblance for more than a minute or so or they die/pass out for 7 days." (I've actually seen someone put this as a part of the description of their semblance but I can't remember the actual semblance) Why?
