This is how skins should work
"Hitting a Runed target is considered a "miss" until the rune is gone.
This is why melee procs will not go off until the rune is gone.
You do not suffer melee knockback while runed (spells can still push you around and stun you, however).
You also filter the Rune-absorbtion messages in your chat windows by setting "You being Missed"."
They do not
Here's a link of player's describing exactly how Rune and Skin's worked, I just remember from pvping all day that melees had to strip my skin to interrupt me with pushback, although stuns like bash and spell pushback still landed through skin.
