Essence Reaver
Essence Reaver is a new item that was added in Patch 4.10. It's an alright pickup for AD casters.
Or at least it would be.
In Patch 4.12, Essence Reaver gained another damage buff from Patch 4.11, where it received a damage buff to 60 AD. Now it has 80. A damage buff isn't what it needs. What it needs is to actually be a viable pickup in the early - mid game, where mana issues are real problems. As it currently stands, Infinity Edge is where AD itemization has moved to. Dispute it if you want, the nerfs around all of the other AD items and the huge buffs on Infinity Edge means that AD champions with the highest ranges could make the most use out of it, with the least negative impacts to their build, which is why Kog'Maw and Tristana are now top tier picks. With that in mind, AD itemization around all other champions who don't have high ranges and can't make the best use out of Infinity Edge (ex., Vayne who's weaker now because of the BOTRK nerf) have sub-optimal build paths trying to compete with the more superior Infinity Edge rush.
Now why did I even talk about that? Because right now, it's an incredibly viable pickup. Essence Reaver is not. Pretend we're talking about
. If an
player was having mana issues in lane, the first thing he should think about is a Manamune. Why is that? Because it is an affordable option in the early game which gives him a larger mana pool + mana regen when he needs it. By that time, if you're going to finish the Manamune (which you should), you have the mana you need to transition well into the mid game, and Essence Reaver is no longer an item you need to build, because you have all the mana you need to fight. It's an incredibly cost efficient item for what it's worth, and for what it contributes to a characters stats. Even if this Ezreal had the money, he likely wouldn't be thinking, "I need an Essence Reaver right now". He'd probably have Iceborn / Trinity force on his mind, or Infinity Edge, or Armor pen to save up for later on.
What I'm saying with all of this is, that if you need mana as an AD caster, Manamune is always better, because it has an affordable recipe item in the early game which contributes to the thing you need as an AD caster -- mana. You simply cannot afford an Essence Reaver in a timeframe of which it would be the most useful. Stop buffing the damage on Essence Reaver, and give it a mana-on-hit recipe item that would actually make people choose whether or not they want Manamune or Essence Reaver as an early game pickup. Obviously it should be far weaker than the finished product for balance's sake, but it would make AD mana regen items more diverse across the board. It would actually be an item to consider if that were the case.
