CC reduction is worthless, yeah. The values are too low for them to matter at all, and I’m not a fan of CC reduction as a mechanic in general… I feel like if I have a skill that stuns someone for 2 seconds, they should be stunned for those 2 seconds. It should be replaced by another effect entirely, in my opinion. It IS a helmet, make it critical hit protection.
But if it has to stay, then the values on it have to be in the 30% to 40% range for it to be worthwhile. Halving it may be too heavy.
