Guild Wars 2

I’m focused on spirit weapons build (not totally pure) and got specter/focus & mace/torch.
This is my build > http://gw2skills.net/editor/?fUEQRApf7dlcgSBHCSHEg4ESmCWCBresPyT+gpQj8IA >> copy and paste if not worked.
1- Which is better Writ of Persistence or Writ of the Merciful ? ( which gives me more healing ) as I’m using mace and focus ( their symbols provide healing and regenerations ).
2 – Is there any use of Shield of the Avenger against melee foes?
3 – which is more useful > Shield of the Avenger ( blocking ) or Bow of Truth (healing ) ? ( your opinions and reasons )

Stick with the shield. More often then not your shield will mitigate a high damage attack which will work out better for you then trying to heal it.

Mitigation is better for solo play. Healing is better in groups.

1 – Which is better Writ of Persistence or Writ of the Merciful ? ( which gives me more healing ) as I’m using mace and focus ( their symbols provide healing and regenerations ).
2 – Is there any use of Shield of the Avenger against melee foes?
Any answers ?

1 – They are both viable, so my best advice would be to test each one for a period to see what works best for your play style

2 – If you like running with avenger slotted, but run into melee foes, then you cast it and immediately destroy it for 6 seconds of weakness.

3 – Personally the bow’s healing is pretty poor and hard to target if you’re trying to heal allies, and the condition removal is too slow and random ( I’d prefer if they swapped the command with the passive effect ).

Avenger is often underrated, but pretty awesome against ranged foes, especially in dungeons where you can save your team from 90% of ranged attacks – especially if you have traited for extended spirit weapon duration.
