Arguing they’re ALL “valid and rich” for the mere sake of it, isn’t really valid … 
it’s simply catering to some obnoxious virtue-signaling notion of praising for the mere sake of performative empathy and moral superiority.
Mind you, MANY troll tribes – Amani included – had man-eaters & cannibalism.
Some STILL do.
They had – or have – slaves either abused, beaten & chained into submission or bewitched by voodoo, along with sacrifices to their gods and various hex magics to torment those they consider ‘lesser’ added in with them also performing necromancy and frequented skirmishes + raids that butcher villages entire.
… If they’re ALL “valid and rich” – You’re claiming such for even the Vilebranch and the other tribes of who practice cannibalism, mass sacrifices, torture, dark-magic slavery and genocide of what such tribes consider ‘lesser’ are ALSO valid and “rich” in culture 
I’d argue that conceptually — They’re cool and valid in the sense they have self-serving benefits to it, but I wouldn’t be ignorant enough to claim or insinuate it in such a way that they’re culturally rich in any morally virtuous ‘valid’ sort of way. lol
Yes - Implying it could be better …
Wanting to upgrade architecture in advancements to what they once had, further the architectural technology (waterfalls and river-networks) and further advance them in strength, vast riches, opportunities, magics & divine powers isn’t a bad thing. lol
