How is it poorly executed?
The general arcing of the plot is pretty predictable. The trifecta of "humans-advanced aliens-consuming alien horde" has been done to death, and is older than my grandmother......literally.
The "SPARTAN-IIs were what kept humanity from being killed off" is pretty much "The Adeptus Astartes are the only thing standing between the Imperium and destruction", except it's actually true, despite the incompetence of Covenant ground forces, and the sheer awesome badassery of the 40K Marines.
Snd I was thinking of how to take down the Death of Ruin and other Imperium ships, and the only thing I could think of with my limited knowledge was the Forerunners or the Precursors and they are both from Halo
Unlikely. WRT the Precursors, no information is known about them; there's no way to tell. WRT the Forerunners, it's somewhat the same, except that we know that a Forerunner Dreadnought (the Keyship of Halo 3) can easily withstand bombardment by multiple MAC cannon.
Which is actually par for the course for Imperial adamantium hulls.
Oh and sorry for some of the comments on your fanfic, cause most of my warhammer knowledge comes from a game or my Tyranid codex
Don't be sorry. Feedback is feedback; it's not like you were flaming me.
Also has anybody here read Outliers by Malcolm Gladwell, I'm asking since it is the most interesting book I've read in along time
Nope. Don't intend to either; it sounds&looks kinda hokey.
