I have never, in my 400 hours of playing this game, noticed the secondary effect of this skill: “skill cooldown increased by 66%.”
When I am chilled and I activate a skill it has its normal recharge rate. Has anyone else seen this not work?
In any case I suggest that, instead of increased CD, chilled gets changed to and skill activation debuff. Maybe 66% (considering chilled short duration) or 33% if that is too much.
