Hear me out Akali players
take a seat get ready to salivate:
the future akali build could go something like:
okay so far so good i didn't scare none of you.

In the link i added I discuss the idea of creating a new auto attack damage amplifier for bruisers. http://boards.na.leagueoflegends.com/en/c/gameplay-balance/FKazxyxF-bruiser-crit-modifier-crit-base-damage-on-select-items
start of game drink potion to switch from default item stats to its new secondary stats for select items.
:
UNIQUE: Grants +1 % chance** to crit base damage** for every 3.5% of missing health, capped at 20% chance.

new atmas could give 40 armor 10 cdr, 20% chance to crit base damage and +25% to crit damage.
Now you'll probably be thinking, ya but why lich bane you aren't stacking enough ap to make it worth while...

Triforce's 30 ad and ap and 8 movement speed is comparable to lichbane's 80 ap and 5% move speed (in fact with just those bare stats triforce holds a bit more gold worth). For 700 more gold triforce has HP, crit and attackspeed to boot, not to mention phage passive. And its sheen proc does considerably more damage off the bat compared to lichbane as a standalone item. Not to mention it can lifesteal off the spellblade proc, lichbane can't.
I don't see any reason why lich couldn't be rearranged such that it could have two equations; one for ap champions who likely wont exceed 300 ap, the other for ap carries with upwards of 400 ap.
If equation #1's dmg is greater than equation #2's output than equation #1 is used.
in other words spellblade would deal magic damage for the greater value between:
Equation #1:
... deals 160% base AD magic damage (+ 20% AP) bonus magic damage.
Equation #2:
... deals 75% base AD (+ 50% AP) bonus magic damage.
Best of all lichbane could spellvamp on portion 1 of the equation at 50% or 75% reduced effectiveness making it comparable to lifesteal
Attack speed is pretty good on akali, her passive gives her like a built in nashor's tooth for each of her autos. It would also syngergize greatly with the 40% crit chance you'll have from atmas and maw.
