IMO, many of the combat scenarios in the MSQ are poorly designed.
I say this because many take away from the story and destroy immersion, rather than support the story and increase immersion.
Being dropped out of an emotionally engaging and significant story cut scene into a frustrating (non-intuitive, no instructions, play as an NPC) and/or long and boring combat scenario (bullet sponge / invincible enemy, one damage ability NPC) doesn't endear me to the story, it just ticks me off.
Stop making me play as an NPC with limited abilities (unless it's a short and engaging scenario with a satisfying and NPC fitting 'auto win' type conclusion - see the Ruby Weapon scenario in post ShB for a decently done NPC scenario), stop expecting me to keep NPCs alive if I'm not a healer (and even then put them in party with me), and let me pick the difficulty upfront (more to avoid crap like failing to some 'haha gotcha' gimmick or an idiot NPC standing in bad and dying while the boss is at 2% after wasting ten minutes fighting pointless trash and spamming one ability at a bullet sponge)
