Manamune is my favorite item in the game. I understand, I wish I could include it in all my builds... but, it's just not priority... and by the time I can afford to say "Hmm, maybe I'll get Tear/Manamune now." there's not enough time left in the game to put stacks on it.

If I were to suggest any sort of buff for the item, I'd suggest basic attacks to grant 1 mana on a 2 or 2.5 second cooldown, rather than 3. That would be more than enough for me.

manamune is awesome. Quite a cheap item that grants tons of AD at the 1000 mana mark.

With other mana-heavy items and at the 1000 mark, Ive had my manamune granting me near 70 Attack damage (90 including the stat)

If manamune grants more AD in % than AP archangel gives, I'm building ryze whit 5 manamunes

First off they would need to make the 2.5 - 3% AD from mana unique something that should be done with archangels.

As for my thoughs on this: I think you just found a great Brutalizer build idea that doesn't come across as super broken.

I would bump it to 3% of mana pool turns into AD given that champs such as talon have 980 manapool base at level 18 +1350 from fully stacked Manamune is 2330. 3% of 2330 is 69.9 so it would end up being 70AD from the mana late game for a total of 90AD

60.5AD fully stacked + .03 * other mana
20 armor pen
15 - 20% CDR
1350 mana (fully stacked)

This would actually be a really good item for actual AD casters but might result in AD carries going crazy with abilities so it is a fine line to be walking.

The only champ you forgot to mention getting Manamune all the time is is Urgot who really does need it.

I hope that this is at least looked at because it does seem to be aimed in an AD caster direction but might still prove to be to AD carry friendly with ashe spamming Volley every 3.2 seconds however if it were to cost say 2800 then most AD carries would likely pass on it given that they could be getting a BF sword and pickaxe instead for that would still be better off getting inf Edge.

Urgot, WW, Skarner, and Trundle would like a word with you.

Point is. Its perfect for solving mana issues on Tanky dps chars. pair it with say frozen heart and you'll be pwning face.

Note: why does nobody use it on MF anymore? it used to be one of her best items.

I already got my solution :P give manamune and upgrade that gives 20% spell vamp and another 10 ad, and the new recipe would,contain a longsword + some more gold :P

You are completely wrong, and I don't feel like explaining why atm.

Berserker's Greaves
The Bloodthirster
Phantom Dancer

standard ad 3 core item build

4rth item is usualy a IE

this is why people are saying manamune is ****, because it needs to be your 1st item if you ever want to get fulll benefit of its mana increasing passive and turning sad mana into AD
but buying it as one of the 3 just dusnt provide the same power and stayability as
Berserker's Greaves, The Bloodthirster, Phantom Dancer

The problem there is the CDR. Changing Brutalizer for Hexdrinker, Madred's Razor, Phage or just a Pickaxe to keep the near the same price with your price addition may be better. Bilgewater Cutlass would also fit but it would be more expensive. But idk, all options feels weird. Pickaxe, Brutalizer and Hexdrinker are the ones that feel less weird imo.

I would say giving Manamune spellvamp would go a long way to making it a viable option for a few more champs.
