Instead of replacing Zeke's with another item, why not just ADD an item?
Why does Riot feel like we need to be capped at a specific number of items in the game? Why can't we have both?
As it stands, Zeke's is the one aura item that actually helps AD casters, and acts as a nice analogue to what Abyssal does for AP champs (was closer when it was Stark's, but still). Players just got done expressing how much they dislike losing magus to get runeglaive, and it's a sentiment that's been expressed in the past (probably will be again if you decide to push through the Abyssal replacement)... and now you want to push Zeke's out? I understand it's not the most popular item, but it's actually GOOD. If you want to look at helping items, how about starting with the items that actually suck (every other support item besides Locket/Zeke's/Crucible/maybe Censer).
Also, on a separate note, can we get MORE manaless items rather than fewer? It opens up so many more build paths when I can choose to get my mana on one item and not have to double down on it. Is Zekes' 250 mana going to be enough to sustain a build that needs mana? No. Are there other items that don't sustain a build by themselves, but count on picking up another 250 mana to help you do so? No, it's a bit greedy for support to count on that. Please let us keep old Zeke's if you feel the need to push this item into the game.
