Yes, their cutie marks also reflect on their personality. If your pony's name is Sassaflash with a lightning bolt cutie mark, you could guess she likes weather. These ponies lack the those two things, making them just boring toys that you can't care about right when you see them, because you don't know about them.

In other words, MGA is lazy and boring.
