Unicorns. G3’s biggest failing was the lack of more unicorns. Also love the SLH and winter ponies.

IMO their second biggest failing to having no canon Boys. But yep they should have had many more unicorns than they did
Their third biggest failing is having the symbols on only one side...
These issues aside, plus the overuse of pink, I love G3s & think they're gorgeous. They're the college students of my Ponyworld, & Celebration Castle is their college.
