I'm still an advocate for smart bimbos, so I hope there is some leeway for heart full without the head necessarily being empty.
I like my champion being intelligent, and also like it when it isn't tied to the Cunning stat, because that creates an artificial limitation on the roleplaying potential for specific classes; so I don't personally find any dissonance between witty behaviour, and optimistic, fun, loving, sex obsessed and bubbly scenes.
I do agree with Burnerbro in that I liked Trials empthasis on scene changes and specific sexual content alterations instead of minor personality quips during conversations (although I do appreciate the omission of degrading/insulting snippet's and connotations on intelligence), there are very few scenes I've encountered that actually seem to actually utilize the bimbo fetish in a stimulating way, or to support sexual encounters.
