I would make a new talent in Retribution Tree :
-"Wisdom of the Martyr" 3/3
Gives you mana equal to 5% /10% /15% of health lost by all damage inflicted by yourself.
It also increases your expertise by 1/2/3
And the Glyph of Seal of Blood/of the Martyr would be:
Increases the damage done by your Seal and Judgement of Blood/of the Martyr by 5%
or Increases all damage you deal by 2% while your Seal of Blood/ of the Martyr is active
