You're right. Let's instead compare Wrath of the Righteous to its predecessor: Kingmaker. Kingmaker's story is fairly serviceable, nothing amazing, nothing great; but functional. A group of adventurers are invited by Lady Jamandi to seek out an infamous bandit lord, dubbed Ruler of the Lands. This bandit lord, dubious in his claim to rule, has been causing havoc to neighboring states. Levying taxes, et cetera. No noble will ever recognize this self proclaimed bandit lord. There's also the fact that nearly everyone has a claim to the Stolen Lands. So attempting to make true to that claim will result in war between every neighboring country, but a bunch of unknowns on the other hand. That's different. Using this opportunity Jamandi sets up her own expedition, finances them, all in effort to establish her own puppet state that acts within her interests.
Of course, there's also an extra layer of Fey invading the Stolen Lands. Lantern King setting up curses and pranks on the denizens. A certain Nymph bringing Kingdoms to their demise, and so on. Kingmaker may have not done the greatest job of executing its story. However, that set up right there is ten times better than Wrath's plot. I wanted to dunk my head in a bucket of boiling acid after reading those, quite frankly, embarrassing dialogues in Wrath.
Good grief.
