i never cared much about "power levels" in the MLP Universe. For me, it's a pity argument to not like certain characters like Twilight, Starlight or Luna.
I like most of the characters in the show. However some of them have fan bases that leave a nasty taste in my mouth. Puts me off of their “perfect waifu” characters and just makes me want to avoid them. Which is unfortunate because it’s not the character’s fault.
