“Blueprints aren’t what I thought they were, so please redo them from the ground up, either breaking every existing UE4 project in the process or creating a parallel codepath that will exponentially complicate the entire engine maintenance”

PS. If I sound like a jerk, good. Requests like these are inane, have no place in what is presumably supposed to be a community of intelligent, mature developers; and are probably in large part to blame for Epic developers not being as active on the forums as before. I wouldn’t want to explain why there can’t be a “make an MMO” button for the umpteenth time either.
