If you dont know, there are "gamebreaking" (loosely termed) bugs for Fiora and her vitals. Basically, Ludens Echo procs them, along with the Hextech items (
) and the BORK active does too. Basically, if I were to go AP, my build would probably look like 
which honestly doesnt look good on paper but I think this could actually work lol. Hopefully I dont get flamed but wish me luck Im gonna try this when I get home from school.
Kaioko2 votesIf you don't build AD then your vitals won'tn deal damage. It doesn't matter if your proc them or not at that point. Even if you managed to hit all 5 vitals (1 start + 4 ult) you'd deal 12.5% of a targets health which is laughable late game vs. the 50-60% true damage you could be dealing had you gone AD.

Is it meta?
Sire Hippington1 votesit looks bad on paper because it is, unless i miss understand the bug. But as it sounds, it has nothing to do with ap but instead with any form of damage beeing able to proc the passive. Howeverm her passive does next to no damage without AD, so even if you can use ludens and co to proc it often, the procs will do pretty poor damage without AD so the built will suck. Also, the hextech items share their CD, so gunblade+protobelt is not that great.
Bent Pixels1 votesBasically if youre standing to, say, the right of someone and you use the gunblade or BORK active it will proc a vital if said vital is on the right side of the enemy. Same with the other hextech items
Sire Hippington1 votesyea, so AP makes no sense at all as you're vitals will hardly do any damage even if you proc them...

this would make bork a consideration, but if you build ap, the vitals do shit for damage. so whats the point of being able to trigger them easier?
bork could fit into a regular fiora build, or just grabbing 
for the lane phase and sitting on it to use the active.
but otherwise, it sounds like a horrible idea.
