in his Fate stories? maybe, dunno, i just disliked his Revenant Shirou enought to ignore the author, especially with the Contract and Weapons asspull.
but the guy DID plagiastardize (plagiarize and bastardize) Naruto fics, but that's another thing (wich i had already forgotten by the time i became interested in Revenant blade/sword, then the asspull came and he suddenly went Chuck Norris on EMIY, Gil and Turned an ambush by True Assassin against it (after Shirou had just WTFPWND EMIYA or GIl i don't remember clearly), as easy as pie... i called bullshit on that and subsequently ignored it.
it's Inherently bad or horrendously written? no.
is it OMG GOOD? also no.
what it IS is a YMMV fic, not good or bad enough to be really praised or loathed, but sufficiently 'average' to be uninteresting.
and no it's about someone Stealing Fics as in complete scenes, plots and dialogues, recoloring them a bit (changing names and places) and then claiming that everything is a product of their own creativity.
heck FF writters do disclaimers (because everyone knows that they are just playing on someone else's sandbox) and when using someone else's plot, character, idea they also thank or at least give the name of their inspirator AND gave it their own spin.
and now that i remember the incident it was his Hitsugaya/Naruto Fic wich was just a recolored version of Fosfor's, it may have changed the contents or it may have diverged from the path of Crimson Blade, but at that point it was just a recolor and it had a chapter or AN especially dedicated to him (namecalling and the like).}
also he tends to fanwank his characters a bit too much, a bit too sudden and a bit too stupidly, sometimes.
it's a Meh author and he 'publishes' meh stories of the YMMV persuation.
