No no, that's not what I'm saying at all.
The competition was broken from the start - it emphasized one competitors skills over the others, making the other competitor feel like she needed to cheat in order to prevail. The main issue is, there's no real sense of balance. The two have extremely different skill sets - not just on a personal level, but
racially. It's like holding a triathalon between a human and a cheeta - the cheeta's going to beat you on the running hands down, but it's got no chance against you on a bike. It's not a fair judge. I honestly don't think that there's any way to directly compare the races 1-1, because they all have radically different skill sets and physiology. Earth ponies are tanks, pegasi are fast and agile, and unicorns are highly dexterous. And each fails at it's counterparts skills.
That's the issue here - no matter how good one pony looks in an episode, it's hard to compare them to any pony but another of their creed. So while we can call fluttershy more graceful than RD, and Twilight more magically skilled that Rarity, what can we call AJ in comparison to Pinkie? She runs on
Rule of Funny - if it were funny for her to out wrestle AJ, she could, even if it made no logical sense.
You're definitely right, though. What AJ needs is a nice good episode where she does something on her own - if nothing else, it would validate the lessons about her needing somepony else's help every now and again. She has to have a reason for all that pride, after all. Or at least an on-screen one, rather than the informed abilities we get in applebuck season.
