I leave it at 1 aswell. I only use it for the skill cooldown effect. As I understand, the crit rate buff only last the counterattack duration, which only last 2 seconds. The talent points are more usefull in other skills such as Capote. I put most into Faena which is debatable. It has a long skill effect, but i find it quite useful in mobbing situations.
Edit: As a fencer you should be able to reach critcap with end gear aswell, rending that crit bonus useless anyway.
