I don't really think Ocean Manipulation is a medium skill. It encompasses everything in the ocean and imo it's too OP, and kind of vague since it controls literally everything. Like, you state all the things that Suki can do with water which means she has way more skills than any of the other characters. It would basically be like if someone put on their CS "Can control everything about their element and things associated with it." I'm looking for skills that are at least a little specific in what they do.
Edit: To clarify, it's fun to make someone who can control everything about an element, but I'm interested in girls that don't control everything about it, but use it to their advantage and can come up with creative spells and attacks with it? Do you all understand what I mean? So, that's what I'm asking for, is to water it down and create skill sets.
