So this is what we're doing now? Nerfing Sterak's because Graves abused it?
Sterak's Gage Health lowered to 400 from 500.
Let's take a quick peek at the top champions in the game shall we? For solo queue we have:
Top
Mid
ADC
Jungle
Support isn't involved in this
Top LCS/LPL/LCK picks:

Now from this list, the champions that actually build Sterak's:

Are
you
seeing
a
pattern?
Do we really need to dumpster yet another juggernaut item because an ADC is abusing it? It really baffles me how out of touch you guys are with your game, with the triple ADC meta going on in the asian scene and our own double AP/double ADC meta going on here. If you haven't noticed,
are the only tanks actually being played, while
are the only melees currently abusing the "juggernaut" itemization.
Can we nerf the shit out of your 57% win rate ADC and 95% ban rate pirate before dumpstering another item? Losing 100 HP on
was painful enough, now my entire
build is going to be down 200 HP?
I've already been barely playing this game due to the atrocious Dynamic Queue you forced on everyone, this is pushing it.
Edit: To clarify, this is a problem with ADCs in general building
as a defensive item, but Graves is the worst offender of the lot. Not only that but a 100 HP nerf to Steraks will keep it just as effective for carries while making it shit for bruisers, because carries don't have resists to back up the HP while bruisers do.
Think of it like this:
has 30 armor post penetration
has 150 armor post penetration
100 less HP on the item means
has 130 less effective HP against physical damage, while
250 less effective HP against physical damage
If the item needs to be nerfed that badly then fair enough, just don't ruin it for its intended class like you tried to with 
, and they could make a special case for him.
and
dating back to Worlds. Since then, adoption has continued to rise. The use of the item by roles it's not intended for is a pretty good signal that it's too strong.
