Suggestion: AP balance for counter-attack and ambidextrous

The ability "counter-attack" and the ability "ambidextrous" have the same ap cost.

With counter-attack the unit has:
- a malus to the defense value
- a free risposte attack when an enemy misses

With counter-attack the unit has:
- a bonus to the defense value (that cancel the malus of counter-attack)
- a free risposte attack also when an enemy hits

So I propose a quite lower cost for counter-attack and a quite higher cost for ambidextrous, or alternatively, no defense malus for counter-attack.

Agreed.
Basically, counter-attack is nearly worthless without ambidextrous.
