I never understood the "sniping" issue. If another translator can translate the work, he or she is free to do so. Don't get this dibs mentality. It is not the other translator's if you are not able to keep up with the releases. You are also not forced to translate. If you think you can release a chapter with better quality but at a later time, you are free to do so. I'm sure there are readers who will read and appreciate it.
Ultimately, scanslation groups do not own the manhwa. The author does.
