This is my hot take:
Most comics creators are artists first, writers second, and it shows. I think that's where the whole "you don't actually have to be the best artist to succeed" thing comes from - because really great comics writing is rare, and so it stands out when you come across it, even if the art isn't as strong as what it feels like it should be for the level of popularity.
It's funny, because I think there's a bit of a paradox - drawing the panels takes WAY more time than coming up with/scripting the story. So it feels like making comics IS about the art, but when the writing is weak, the whole project can really suffer. I've read a lot of indie comics that I want to love, but they're bogged down by their writing, even though the visuals are beautiful.
I have a lot of friends who are artists and a lot of friends who are writers, and it's struck me that the only ones who ever seem to try their hands at making comics are the ones who are artists, even though you need both skill sets. Obviously, these are giant generalizations, but it's a trend I've seen. Overall, I think writing for comics is really, really hard, because you need to have that visual brained piece, but also the more analytical, language focused ability too, and those don't always match up in people.
So yeah. Kudos to all of you who are writing your comics! It is very hard to do well.
