If people think you're writing fiction just for VSBW, you'll be rejected from the start.
My suggestions; Writing fiction as if VSBW didn't exist quite normally.
If you have a special interest in the power system and want to create strong characters in the editing you are going to write, then you will need to keep cosmology consistent, processable, and strong.
The story, plot, theme, conflicts, psychological fiction of the fiction and the characters in general should be processed consistently.
In addition, having your fiction published by a publishing house will further increase the chances of VSBW accepting it. Of course, the most important factor is that the fiction is recognized in a certain amount.
