I saw an accomplished comic artist on twitter criticizing the the default oval shapes for speech bubbles and immediately stopped using them. So the lettering is going to get even more awkward for a bit. Lettering was my least favorite part of comicmaking until recently when I started doing it in CSP instead of Photoshop and it became much easier to do. Typing dialogue, making it into an acceptable shape, putting a bubble around it, and then adding a tail is always going to be tedious but at least it goes fast now.
