I liked Ran'jit. If anything, he was underused - but then I think Eulmore should've played a bit of a larger role in 5.0 overall to better explain his motives and reasoning.

...and honestly, if the protagonists are going to be written with plot armour at almost every turn then there's no reason why the antagonists shouldn't get to enjoy that same treatment to a lesser degree. Personally I'm hoping that the 'Echo' and 'Blessing of Light' are removed at some point in the immediate future so we can go back to being an adventurer, though that's probably too big a wish when the plot seems set for grander and grander stakes each time.
