Something similar to me, but in a different manner. I always run the first map blindly, often the second map too. If it is star rush, i will probably run a fair deal of them blindly and check videos for the last ones. Depends on the stamina cost. If it is a collection or farm event where i want the character maxed i will check videos after the first map. If not, i will only check on the 1-2 last ones.
Edit: Seems tomorrows event will be Horus according to faesbuk.
