I wasn't familiar with that. Rulers I know Asuryan to be a patron of, judges and lawyers are new to me. I guess that makes the idea that Hoeth/Verena is a God of justice and just doesn't do its justice thing in the elf pantheon make more sense, but again even if we take this to be correct it doesn't really prove that Verena predates Hoeth, it could just as easily be that Hoeth gained a new domain. Is there any source that suggests some divinity like Verena was being worshipped by humans before the Coming of Chaos?
According to the wiki the offical stance is "Hoeth was perhaps nice to give us knowledge, but what if KNOWLEDGE IS BAD BECAUSE NEW THINGS ARE BAD", which I have to say is a very Dawi way of looking at things:
Opinion is divided on precisely why Hoeth did so. Most Elves believe Hoeth's actions were founded in generosity, but some mutter darkly of how knowledge leads to progress, and progress inevitably leads to the ruin of tradition.
