Under the condition, that you use BlackoutCombo-ISB every 6 seconds, the value of your purifies actually doubles.
Considering that the stagger debuf can only bleed out half of the time but increases all the time due to boss hits the stagger dot will grow to its double size before balancing out. At that point the dot will tick for double the usual value, but only half the time (due to emp-ISB) creating a balance. It does make the purify way more worth it but the damage from stagger also becomes more "bursty" since it ticks half the time for double the value.
With artefact points in Potent Brews (+ISB duration) the Purify dot goes from +100% to + 66% but still worht it. This does however require way more practise than the other two talents.
For example you should also always try to Purify at the end of emp-ISB. This does however collide with the next BoK and you do NOT want to empower PB. Meaning you have to go BoK-ISB-Filler-Filler-PB-BoK and the ISB has to be as arly as possible and the PB as late as possible.
