Why does SE find the need to make some Quest encounters unbeatable?

The two that come to mind are the R36 MRD quest, and the Ul'dah opening sequence quest. Unlimited HP? Seriously?

What ever happened to being the main character in the story! Everyone in the story is just pushing your character around like you're nothing.

Hell, even the R46 Story Mission (spoilers) has you getting saved by your guide NPC. I didn't grind to R50 to get saved. I want to kill something. I want to fight someone epic. Not play foursquare with a giant robot and get saved by a catgirl.(spoilers


SE needs to get on top of this >.>
