jars is bad, doesn't understand how AP ratios work.
A .2 ap ratio, when you cast it 4-5 times in one combo, thats a 1 to 1.2 ap ratio. How good.
Maybe you should go learn mathematics jars, and go look up the actual numbers. There is a helpful explanation on DominateDominion.com proving that AA gives a huge damage upgrade. Unless you need the sustain, upgrading that tear to AA can be better than WoTA. Depends on the situation, but doing more damage makes you more unkillable because the spellvamp gives you more health, and they take more damage.
I never said rush AA, THAT is just dumb
