Akali's changes were somewhat negative.
I tried Akali recently and ended up with 35% CDR. The issue is that I ended up with a 0.679 second.So basically this is useless because since it doesn't proc her Q anymore either you waste energy use it and have it up again immediately or you Q -> Auto -> E but can't E again since it uses too much energy. This truly was pointless and is slightly annoying.
