Training Regimen World Quest

Why does Blizzard keep making World Quests that hinder storyline quests and vice versa? How, as players, are we supposed to figure out that you cannot do the World Quest Training Regimen when you also have the story line quest Phalynx Malfunction and the follow-on quests? I do not play the game to figure out weird interactions like these. This is about the fifth time I’ve had to go searching through Blizzard and other websites to find this sort of interaction. That is flatly annoying and shows disrespect to their customers. If I programmed like this in my career as a programmer, I would have been fired.
