Also xb1 players might not know this but we were told that roughly 50% of main hand AP is added as hidden AP to awaken ap. The accuracy from main hand is also applied which is what initially made kzarka so desirable. What is important to take from this is that AP accessories are extremely desirable as they add both awak AP and main AP.

With the addition of absolute skills certain main hand abilities are actually viable and may become filler for awake rotations.
I know this doesnt directly answer your question but there really isnt a known awake/main AP comparison outside of just testing all skills and keeping those that prove worthy of pve/pvp. AP for different classes scale differently (have fun with this constant annoyance) so the ratio estimated for one class wont be the same for another.
