Elementals probably not. (But maybe yes in certain situations?) Demons and angels show some signs of intelligence most likely muffled by their subservience. (You gotta plunge all up into Chaos and make DARK PACTS with OLD DUDES who seem to have AGENDAS right?) It's possible angels have similar LEADERSHIP dudes who just don't care enough to extract promises just for symmetry sake?) Nature spirits from Dendara can talk(They come off more like allegorical spirits of animals than THE DEAD SPIRIT OF A RAVEN or etc.) But I think the scale of intelligence in those beings is probably hierarchical or based off the age/power of the creature. (Like the ANCIENT spirits are all WISE and MAJESTIC where the more mundane ones seem more rudimentary)
The nature of elementals is to be single faceted but the line blurs in a couple examples like the mage ents (It's possible the appearance/etc is something the mage builds as a construct?)
the % of both is influenced by multiple factors, armor class, str for divert or dex for dodge, and trans avoidance lets you do both at the same time so I doubt most obsessive testers bothered figuring it out.
