I ran double debuffers for Taurus Cup and won. Take it from me. Frenzied and trick are wastes of your time. If you stumble upon them and have SP left over at the end of your run, go for it, but do not waste a single breath actively pursuing them.
Perfection is a target, not a mandatory outcome. You don't have to have a perfect debuffer with every single debuff, just need to not be a lazy brainlet like most people were in Taurus not even trying to get debuffs that matter. You have no idea how many times I checked other people's NNs and saw like 3 red skills and thought "damn if their debuffer wasn't complete ass that 3rd guy's golshi would have lost by 3 lengths."
