Stormrazor is a complete joke of an item in League.
It has the same problem that Banner of Command had. You don't know how to balance this item properly and on the PBE you are nerfing this item again. If you don't know how to balance this item, why not just remove it like Banner, you didn't know how to balance Banner properly so you guys took the easy way out.
You made Stormrazor such a problem that all ADC champions need to rush this item, and ADC champions that cannot build this item efficiently are considered garbage. You made this item for ADCs, then you overbuffed this item then that makes other champions such as Wukong and Gangplank start abusing this item when the item isn't meant to be brought on them.
Have you noticed that ADCs are the biggest problem with this current game. Stormrazor gets buffed because you nerfed ADC champions and them you buff ADCs and do other stuff like crit items gold decrease. ADC champions abused Lethality so you nerfed Lethality items. ADCs couldn't kill tanks, so you nerfed tanks while increasing their damage so now full tanks basically die in the same time frame as a bruiser/off tank champion. You also removed mages bot lane, now ADCs do what they want in lane while scaling up to late especially disgusting champions such as Draven and Jhin.
. They really dont need the item to be good.
etc to one shot adc or if they not able to take care of adc like that adc will melt them.
such simple champion kit doesn't need buffs in first place but got to sell that sweet vs event skins.
. THAT'S DISCRIMINATION!!!
, reduce the damage of its crit, and allow it to charge up via AAs instead of through not AAing.
component that makes it so attractive to other champions and assassins especially.
extra ranged passive with Stormraider's, i think it would be problem solved, assassins and most bruisers dont build att speed exclusive items.
is actually a crit champion. He almost always builds full crit after 
are usaully the only items I ever see on Gangplank anymore.
nerfs reflect that and
