The only recent Blizzard games I've played are the installments of Starcraft 2, in which the plot has wavered between "serviceable" and "goddawful stupid". And, for some reason, the finale of the story also has to be the climax of the stupid. I would think that the game makers would want to end on a scene that makes the audience want to empathize with the main characters or admire them rather than want to throttle them for their gross idiocy, but what do I know?
The particular idiocy in Wings of Liberty was Raynor's indifference to the fact that his buddy had a bomb wired into him and was obligated to take orders from a shadowy somebody or other. Jim Raynor is an idiot. The shadowy figure turns out to be Mengsk, who inexplicably lets Findlay run a gigantic mech through his capital city. Mengsk is an idiot. Findlay, too, I guess, but he's at least in character.
The idiocy in Heart of the Swarm was Kerrigan twice unnecessarily walking into an obvious trap. She has a innumerable horde of expendable minions. If something has to get fried, chopped, frozen, zapped, or crushed, it's better to send a few dozen disposable Zerglings than risk her own irreplaceable self.
And all of these happen via mandatory cutscene. No amount of player skill can keep the characters they are meant to think of themselves as from eagerly sticking their heads into various guillotines. You can't, say, send Findlay off to the other side of the map to keep him away from Kerrigan or throw a squad of Hydralisks into Mengsk's office.
