[WraithLord]

I have made a short experiment as follows:

Pretnders:
Arco:
Virtue, D-6, order 3, sloth -3, heat -0, growth -3, luck -0, magic -2. A6,E4. Awake.

Van:
Blue dragon, D-10, order 3, sloth -3, cold -3, death -3, misfortune -3, drain -2. W9,F9. Imprisoned.

Default settings.

Turn 1
Arco:
Recruit 9 peltast. Virtue to research. Myrmid. Champ prohpetize.
province count: 1.

Van:
Recruit 2 vanhere, 1 vanherse. prophetize vanherse.
province count: 1.

Turn 2
Arco:
Recruit Myrmid Champ and 2 peltast. Invade two provinces - 1 with virtue, 2 with first army.
province count: 1.

Van:
Recruit 2 vanhere, 1 vanherse. Prophet Vanhers invade one province.
province count: 1.

Turn 3
Arco:
Captured two provinces. one adjacent to Van. In this province set defense to 20 and move army. recruit in all provinces. Virtue to search province.
province count: 3.
Van:
Recruit 2 vanhere, 1 vanherse.
Capture province, plague strike and half pop. are dead.
Invade Arco province with main army and a lightly defended indie province with Vanherse and vanhere.
province count: 2.

on turn 4 Van army is defeated. The Vanherse survived but most of their troops died. Arco took medium casualties. In this battle the Virtue was untoucheble and killed Vans units with impunity.

Of course Van could have focused on defense but Arco would have invaded them with increasingly bigger armies.

Now, this experiment doesn't suggest that bless isn't useful. Only that even on small maps its possible to counter if one set in mind that he's going to face a bless heavy nation.
