There is no need to compromise, feel free to go full AD teams people, riot doesnt care
My last game

Show us you actually care riot, and do what everyone has been asking. Make flat apply before %, remove edge of night (no nerfs, removal of the item. if you want a spell shield, get a banshees and suck it up), and this horrid meta will end, and lethality will go to assassins and whisper to marksmen and champions like riven can go fuck themselves because they always break new AD shit coming in. And make these changes NEXT PATCH, because it's not hard to just reverse a calculation.
EDIT
For those wondering, we lost that game. Riven snowballed, and by the time we started stacking armor they were adding whispers to their flat pen and nothing mattered.
DOUBLE EDIT
In response to the "Why did you build SV?" posts... Not factoring in runic armor, SV makes:
one man decimate heal 15% (base 12%) two man decimate heal 30% (base 24%) three man decimate heal 45% missing HP (base 36%)
that's fucking huge, and now I will not respond anymore to the spirit visage posts. Waste of my time. As HP increases, the heal amp becomes more and more valuable, and as their pen increases and they get LW items on top of lethality, the armor I would get with a frozen heart or thornmail becomes less and less relevant. No I don't use mobafire, I use my brain. Frozen heart licks balls because they're all prioritizing burst, not an AS DPS build.
Also, between tabis, randuins, scaling armor runes, darius's retardedly high base armor, and a cloth armor, I had well over 200 armor which gets bumped up a ton for 2 seconds because I had the fearless mastery, which burst lethality builds should be suffering heavily against if it wasn't so efficient to tack on % pen afterwards.
against an all AD team?
