Assuming that I understand the way the mod works correctly, it gives +80% additive base damage per unique status effect currently on the target. That being the case, it will be inferior to a maxed Primed Pressure Point until three different status effects have been applied. Why does CO seem to be preferred when it just seems to be not as effective unless you're also running a status primer of some kind?

Looking for recommendations for a decent primary for Nekros. Ideally something AoE and strong enough to make solo SP Survival runs easy but also does enough slash to mince the enemies up for extra Desecrate procs.
