Saga and The Walking Dead are good examples.
A lot here sell to some degree and would like nothing more but good things come to this book .
If you weren't selling any copies or struggling to get the book out and it had one more chance... Maybe re numbering would help. But like someone said earlier , just for a issue or two. It's just a bandaid.
This book doesn't seem to be having any problem selling, and you are getting a fan base going. Re numbering is discouraging and confusing. Whomever is telling you it's a good idea, I'd like to hear their side.. Because you've heard this one.
Please stick with the system you have now.. Issue #100 of Enormous will look so cool when you get there!!
