Well, enjoy the not-easy-to-read factor of not using more than that line-spacing then, is all we're saying - 'line spacing' is enough for books, but not for stories posted on the internet. And considering the sizes of some of those 'paragraphs' (particularly in the first prologue)...well, you'll probably be turning away a lot of those readers who can't be bother to squint their eyes at a computer screen just to read something when they can read a better-presented fic.
Of course, shouting in GIANT TEXT at readers who try to offer said presentation advice isn't necessarily a good way to attract reviewers either. =/
