Can anyone explain to me attack power vs damage. Looking at my character, with weapons it has:
38.89 DPS
main hand 42-55 / 1.8 sec
off hand 20-23 / 1.8 sec
Attack Power 172 (+12.3 DPS)

Now if I put down the weapons I get:
Main Hand 24-24 / 2 sec
Off Hand 0-0 /0 Sec
Attack Power 165 (+11.8 DPS)

So what does any of that mean?
Also, I have a talen which increases melee damage by 4%. Which number does it increase?
