What I wrote was based on long-ago second-hand descriptions of Old Hrestoli Heroquesting being similar to Arthurian Quests, where the participants just go off into the "Forest" or on the "Road" (probably known weak barrier spots or paths) and run into the Black Knight or the Green Woman, do stuff to or for them, and get some boon. GodLearners took great efforts to pin down the identities of those met in the Quests (and we all know what happened to them), so modern Malkioni questers try to *avoid* identifying them just as much (which will probably have its own problems).
I expect, therefore, that there is a much greater difference between Malkioni Heroquesting (which I presume can be done by any caste member to enhance his/her abilities, or just to "kill" things and take their stuff) and their equivalent of theists' GodWorld Questing, which sounds like something that only Wizards do, to create or access powerful Nodes on the Essence Plane(s). Alternately, the Wizards are lying (or at least not telling everything) to maintain their current monopoly on the means to magical power (certainly reasonable for the Rokari, and probably for the Brithini Zzaburi), and some non-wizard will redevelop Western non-wizardly Questing well enough to make SuperHero (like Arkat did) before The HeroWars come to their end.
