Can Manamune please be buffed?
Manamune has been severely left behind by somewhat recent changes. It was left out of the AD item revamp and passed over when
Archangel's Staff was made more slot efficient. Buffing Manamune will help several of the least popular and most underpowered champions in the game. It will also help provide consistent itemization options since it is currently inferior to its sister item, Archangel Staff.
Below are lists of the champions most frequently building Muramana/Manamune.

As you can see above, Manamune/Muramana is currently only being built by 5 out of 128 champions in the game. The number of occurrences after
Urgot and
Varus fall off to insignificant numbers. Meta-breaking AD Malzahar and AD Blitzcrank builds make up most of the remaining occurences, with a few remaining Kog'Maws building it.
Urgot,
Varus, and
Kog'Maw are all within the bottom 5 least popular marksmen, even when including their play rate in other lanes/roles (AP Varus, AP Kog'maw, Bruiser Urgot, etc.).
Urgot and
Yorick are the two least popular champions in the game, and have under 50% winrates despite typically only being played by experienced players due to their small playerbase.
Champions like
Pantheon and
Kha'Zix really want what is offered by this item, but aren't building it often because of how weak it is in its current state. A fully stacked Muramana is harder to obtain than most alternative items, yet doesn't currently give much of a power spike due to its poor base AD compared to other AD items.
I think this item can be safely buffed for an easy victory for the Riot balance team. Here are some suggested changes:
Pickaxe replaced by
B. F. Sword in recipe.
Combine Cost 775 ⇒ 1050 (Total Cost 2400 ⇒ 3100; This is the same total cost as Archangel's Staff)
AD 25 ⇒ 50
Base Mana Regen 25% ⇒ 50%
Mana Charge: Grants 4 ⇒ 6 maximum Mana (max +750 Mana) for each basic attack, spell cast, and Mana expenditure (occurs up to 2 times every 8 seconds). Grants 1 maximum Mana every 8 seconds.
AD 25 ⇒ 50
Base Mana Regen 25% ⇒ 50%
Most of these changes help make Manamune more consistent as the AD equivalent of Archangel's Staff. I feel that Archangel's Staff was greatly improved when its recipe was updated and it became a more slot efficient item. I'd like the same treatment for Manamune.
With the AD item revamp, B.F. Sword became cheaper, making it a more convenient item to build early on. I feel this would not homogenize
Manamune with
Essence Reaver since the AD item revamp helped distinguish Essence Reaver. Essence Reaver would remain the CDR item for crit users, while Manamune would be distinguished by its early mana Tear of the Goddess build path, Awe passive, and Muramana toggle effect. This would also bring the number of B.F. Sword items (
) closer in line with the number of Needlessly Large Rod items (
).
The changes to the base mana regen and flat AD are to match Archangel's Staff and to compensate for the increased build cost. Increasing AD to 50 would make
Manamune's base AD roughly 77% of the base AD of
or
. For comparison,
Archangel's Staff provides 80 base AP, which is exactly 80% of the base AP provided by
,
, or
. If Manamune were buffed to 55 base AD, that would be a little under 85% of the base AD of
or
.
The buff to stacking rate from 4 to 6 mana is to help
Manamune users stack up a little easier.
Archangel's Staff gains 8 mana per expenditure, and while Manamune also gains stacks for autoattacks, both items are limited to 2 stack gains per 8 seconds. This means that even with this buff, Manamune would still have a lower maximum mana gain per 8 seconds (12 vs 16).
The inclusion of
Tear of the Goddess's passive +1 mana stack per 8 seconds in the upgraded items would also be very helpful. It is fairly rare for an item to lose this kind of functionality when upgraded, and is somewhat annoying. Tear of the Goddess is actually able to gain a higher amount of mana than Manamune per 8 seconds (9 vs 8), which is somewhat counter-intuitive since players expect upgraded items to be completely superior to their components. This specific change could also be applied to Archangel's Staff, which would also help mana hungry mages that build Archangel's and are struggling in mid lane, such as Karthus and Cassiopeia.

. I'm not saying it would be overpowered on him, but it could be a good option and I remember it being considered a viable option in the past.
instead of

if the buffs are decent.
and
as well; and they seem to be in a comparatively good place balance-wise at the moment. If the AD tear path was buffed, those two would probably have to be nerfed as a result.
