Ravenclaws are usually vinculated with valuing intelligence. However, while it’s usually oversimplified in nerds, the true it’s more like they value creativity, side thinking and apparently they could be quirky Rowena Ravenclaw apparently was a master architect and was responsible for the moving staircase, as impractical as it sounds (High base Int, low wis maybe XD)
Another thing to note is that Ravenclaw are the most prone to become masters at their pursuits, and Pinkie is a party master, from games, to arrangements, to party gadgets.
The main problem Ravenclaws often suffer could range from overspecialization, excess of open mind within their creative process, they value any kind of intelligence and not just math, but are liable to be impractical when not well fostered. Luna Lovegood basically.
Plus, Rowena died of a broken heart just like Pinkie suffers from people rejecting her, in contrast with Gryffindor who despite the pain decided to cut his friendship with Salazar because of their fighting values.
