**Essence Reaver Idea: **
Current Build: BF Sword (1550 g) + Vampiric Scepter (800 g) + 850 g combine cost = 3200 g
New Build: BF Sword (1550 g) + Vampiric Scepter (800 g) + Forbidden Idol (600) + 250 g combine cost = 3200 g
Why? Essence Reaver has a mana regen and a CDR component to it so foribidden idol would make sense as a part of it. This would allow people who want to build to get the mana regen and CDR before having the whole item.
Riot doesn't like stats to disappear after upgrading. They put very few exceptions to this rule, and the only one I can think of atm is Warmog's losing its HP regen stat from its item build path, but gaining a massive % HP regen for its passive.
Mana regen keeps going without having to autoattack. That and Essence Reaver's passive mana gain are pretty different.

I see 1 main issue with this:
Jayce was really, really, really OP when he could stack Tear by just switching stances.
While it's usually hard to see what manaless champions gave up, running into a champion that completely bypassed heavy mana-costs in lane without even finishing a major item are terrifying. Like, Image Riven with 1500 range, the capacity to make her entire team fast, and CC that you can't confuse with a latency spike and you've got where Jayce was. Vladimir when you could stack spell vamp caused similar issues.
Resource costs actually have a massive impact on how the game's played, even champions who would never purchase mana like Vayne can see a night and day difference in their lanning phase with a small mana cost adjustment, and Urgot is actually pretty good on the other 3 maps (that global mana regen buff). And by good, I mean Urgot is literally the most disgustingly OP champion in Dominion.
Anyways - MP/5 does become fairly useless at level 18, requiring an item to offer it completely free to really stay even with other big AD items end-game, but as I mentioned with Jayce (and Urgot actually being the best pick on another map) MP/5 is extreemly powerful early-game.
Manamune and Muramana confront this problem by simply making early mana worth what early mana should be worth, and gradually ramping up the item's power as the game drags on and mana sustain plays a lesser roll. Essence Reaver deals with the problem by being expensive enough you don't get the mana regen in lane, but get free mana regen upon completing the item along with competative stats vs. other major AD items.
I'm not sure Forbidden Idol would exactly break the game if it were added to Reaver (it's not exactly free stats and B.F.Sword still forces a bit of a power lul), but adding it into the recipe might still cause a significantly larger power-spike to AD champions in the early game than a lot of people expect.
Also - given Riot's recent hit to mana regen on AP champions, and HP/5 on Mordekaiser, it seems they might be aiming to bring ability costs to a place that's an even bigger, more obvious trade off in power rather than something you can easily erase with half an item.
I would be for this, if it added a mana regen stat, even if it's the same as forbidden idol's mana regen.
