Dialogue heavy scenes: it's gets monotonous when it lasts more than 3 pages and you don't want to get too crazy with the camera angles either(depending on context)
Fight scenes/using powers: had no idea how many of them I wrote until I went to illustrate them. I never thought of my comic as action.
Settings with crowds: I wrote a story that takes place in college and remembered that they tend to have students and teachers wandering around. My next comic is just gonna take place in an empty desert lol
