Face it Riot, no matter what you do, Conqueror is still broken, screwing over tanks and giving too much power to ranged champs. Heimer, MF, Draven, Urgot, heck even Aphelios is using it now. Heck, why did fighters need it anyway? Most have tankbusting qualities and some form of built in sustain, if not Death's Dance.
It's time to face reality; Conqueror's broken, just toss it out. No band-aids going to fix this booboo.
