Iceborn
Iceborn has been in a poor state since it's nerf in 6.8 UNIQUE PASSIVE - SPELLBLADE: AD ratio reduced to 100% base AD from 125% base AD. Ezreal being this biggest perpetrator of it's abuse and it's subsequent nerfs. Then with True Damage creep and Conqueror it has been a sub-optimal item at best much like Frozen Heart (another item that needs discussed).
Conqueror is getting nerfed again which is good but I really think riot needs to consider making this item melee only. Returning the 125% Spell Blade passive and I am willing to trade some CDR for some AP ratio again which has synergies with quite a few bruiser champions who have their abilities split between AD and AP ratio scaling. The item was also made for bruisers predominately in mind and this would reduce the pains of it being used on AA rest ranged characters like Ez. Either that or it needs some health or HP regen added on as pure armor items right now have ( and have had) very poor performance in this current meta and many patches previous.
AP instead of AD
