I really hope..

I really hope that all of these buffs to adcs and anti-tanking itemization leads to some better tank items in the next season. Better MR options would be fantastic. I feel very apprehensive about melee tanks in the coming meta. They seem like they will simply be outclassed entirely. To make up for this, I believe the following changes would contribute to balance - while still maintaining ADCs role as the damage powerhouse:

More health scaling items In general more synergy between all defensive stats (maybe an item that averages out your Armor + MR so theyre equal, then adds 20 to each on top of 300 or so health) Shield items for tanks that scale with HP

Specific ideas include (if all of these were included at once tanks would become overpowered. Disclaimer)

Something with MR, Armor, and health (with no passive, so the stats are worthwhile) An item that increases tenacity and MS when a certain threshold is reached (like 30% health ala , no offensive stats; could also be based on a certain amount of damage like ) An item with an active heal that scales with health (would not replace , which tanks don't take anyway and would be worthless to damage builders due to low max health) Items that simply 'reduce damage' by a small amount. Including true damage. Would have perhaps a small amount of defensive stats. An active item that 'stores' damage over, say, 5 seconds and targets a champion within 150 units to do 20-40% of the damage received to (depending on its other stats)
