Potential for an AD Akali build
I think Riots changes to Akali's E will do very little to help out Akali's more common builds, the ult change may help out a little but the E change will do nothing due to its super high energy consumption.
There is however a way to build Akali that abuses the new lower E CD, AD Akali. This build is going to be focused around a top lane Smite/TP Build as I generally consider flash mostly unnecessary on Akali, but if you wanted to run flash or even Ignite you could easily just sub out
for a
. This build is also most likely to excel with a customised rune page, it may work with a standard rune page but I think you may run into a few too many problems with energy when you don't have blue.
Runes: 9 Flat AD Reds 9 Flat/Scaling Energy Regen Yellows 9 Flat MR Blues (VS AP) or 9 Flat/Scaling AP Blues (VS AD) 3 Flat Armour Quints (VS AD) or 3 Energy Regen/AD Quints (VS AP)
Masteries: Nothing Quite so complex here, Standard 21/9 AD masteries should be fine

For anybody who's doubting what this build could bring
- Your E can deal around 450 damage with a full build on a 0.75 second CD (0.65 with blue)
- You can get just over 75% Spellvamp at full build along with a good amount of lifesteal
- You can spam your 40 energy cost E for about 4 or 5 seconds before running OOE as long as you don't have to shroud
- You regenerate 18 energy per sec at level 18 with blue and scaling yellows effectively allowing you an extra E every 2 seconds and prolonging your faceroll session.

is a fairly good item anyway, I'd maybe look at running it over BT.
