ok fine all Pinkie pie is good for is a battery every thing else about her is completely useless. dose not matter how or what she can do its all completely and utterly useless! she is just a one note joke and that's it. all you need to do is ignore the constant and repeatable abilities because you want to. a power or ability must be completely controllable in every aspect of its use or its useless.
god your really stuck on this and unable to reason on this single slightly off topic post.
why is Fluttershy just under twilight? you think her intimidation power is that good?
