I can't seem to be able to upload images, so I use links from imgur.
this is my character

this is my weapon

and this is the combat log

You can see that my damage dealt before DT is 19.1.
This means my damage before might would be 19.1 / (1 + 0.33) = 14.3,
which is not within the weapon's damage range(16 - 24).
So might is clearly not affecting auto attack.
And another bug:
