So now I'm wondering what notable skill sets we might lack. Since one of Grease Spot's five words is Flexibility and earth ponies get ALL OF THE XP, I was planning on using some of her remaining skill points to round it out. As long as they don't contradict her character, of course.
Yeah, it's possible to say that it's a tad too soon for such final touches, but I would like to get an idea sooner so that I can figure out how/where she learned these skills. I already have ideas brewing about how she went about learning magical theory.
