So now Stinger only builds into AP
Good freaking job! You just completely removed a whole AD buildpath with just an item change. Not to mention it only builds into 1 item now. Also, what am I supposed to do with my Aatrox. I need Attack Speed and CDR.
What I suggest, is keep the AD buildpath from Stinger and keep Zephyr. Remove the tenacity and replace it with a new passive. Boom AD buildpath saved.
and
. 70% AS, 10% CdR, some on-hit effect (possibly a slight on-hit heal - 10 HP or so?). Maybe with Phantom Hit or as stacking flat MS buff a la Udyr as a passive?
sometimes
and as a finisher for most AD builds.
