No, it doesn't.
The thing is, this isn't her only trait. The best thing about Minty, apart from the fact that she's literally the first pony you see in G3, is that after she seemingly ruined everything for everyone in Ponyville, she decided - entirely on her own - to fix everything, replacing Santa, going around the town and giving all the residents of the town the best gifts she can think of - socks - while explaining why she thinks it's the best gift through a pretty song. Minty is probably the most caring pony of G3. It's Pinkie Pie sans all the craziness, which is lovely.
