Yeah, and they've generally failed to impress me with their storytelling. I don't for a moment believe they're going to give warlocks conflict with their patrons because that's not the point of the game, it would just be a tangent unconnected to the main plot or side content. Larian has made a lot of content, but that doesn't make them miracle workers.
Well I mean we know Paladins can rather easily have issues with their oaths and someone shows up at camp to brand them oathbreakers so it's not out of the realm of possibility that Warlocks can have issues with their patrons because it is confirmed that we will be able to occasionally see and interact with our patrons like ask for advice and the sorts. And while that would be side content it could have rather important impact on your playthrough if you are blocked from taking further warlock levels or you lose powers or are punished in a way that you get a major debuff...those would impact the way you play the game in a significant way.
