I hope in preseason flat armour pen is replaced with %base armour pen for AD assassins

Title. % base armour pen is a better fit for assassins and alleviates several of the assassins problems. It reduces feast or famine by allowing a behind in gold/levels case to still be successful (as it scales on the opponent). It makes the ahead case less egregious. It makes squishy targets that buy little armour the optimal targets. It makes itemisation a more realistic form of counterplay, albeit with tradeoffs. Easier to understand and more intuitive than the mildly complicated flat and %bonus pen interaction. (e.g, 50% base + 50% bonus = 50% total) Kills flat pen ADC builds. Doesn't make flat pen builds melee only. Others?
