I think competitive spirit is good. There’s no rule on MD preventing other group from releasing their version of the same series. It’ll be nice if we gets a head up so we can collab on the same project. Still, unnameMinecraft release it under his own gooodwill, no complaints on that aspect.
As for watermarks, many group strive to make their release as clean as possible. Their goal is the same level of art style as the primary publisher. If you don’t mind the watermarks, good for you. But I bet the groups don’t care and will attempt to remove as many watermarks as possible.
I’m assuming unnamedMinecraft read the novel. In that case MTL will do just fine providing context for proper translation/paraphrasing.
Let’s stop before it becomes drama and enjoy the chapters (from whoever).
