I have small amounts of fan service but it's mostly for my own sake, so I don't think it's distracting from the plot. I mean, I could've introduced Roara with her shirt on and not show off her muscles but hey, it's my comic and I can draw what I want.
Personally, I don't think fan service is automatically good or bad. I think what matters most is how it's used. If the main point of the comic is just fan service with little plot, then I'm not interested. But a bit of fan service here and there among the plot is completely fine and normal in my opinion.
