Something that bothers me about Tank Updates on PBE

Just as I thought days ago while you are buffing tanks to make them nearly unkillable you are also nerfing items that counter them - the armor pen

Last Whisper items Armor Penetration reduced from 45% to 35%

Armor increased from 50 to 60 on

Gargoyle Stoneplate 2500g +40 Armor; +40 Magic Resist Unique Passive - Stone Skin: If 3+ enemy champions are nearby, grants +40 Armor and Magic Resist Unique Active - Metallicize: Increases maximum and current Health by 40% and increases champion size, but reduces damage dealt by 60% for 4 seconds (90 second cooldown). If Stone Skin is active, the Health increase becomes 100% instead.

Next possible nerfs are gonna be on items that deal with high health as well Bork and Bloodrazor

I think you should release the new tanks items and HOLD ON with your nerfs on Penetration items else this feels like Double Buff to tanks or Double Nerf and on AD carries. I think we should see how the new tanks items would feel like when released and then if necessary nerf armor penetration and anti-health items if its required
