Well... Hmm.. I have retested the absorb, and now it seems that indeed, the cap is at 40%. I am not sure why the change, since my tests where exactly the same as in beta. So 40% is the new absorb cap.
Also, I noticed another change while doing the tests. I am sure someone has mentioned it, but in beta the pvp penalty was 1/10, but now it seems it's changed to 1/6. I have only noticed this with various sorceress spells (since this was just a side thing while I was testing absorb), in single player game, so the results might be different on realms, so perhaps someone can verify the exact numbers.
