Strictly for single hits like fudo. savage blade ect, would it be kari +1 / Regal ring over niq since QA doesnt matter on single hit ws's?
The only situation you don't want a QA going off is if you messed up and auto attacked an enemy with dread spikes.
R15 Masa Fudo = 3.3 extra fTP
Shining One Impulse Drive = 4.2-8.4 extra fTP
There is a difference between not wanting QA to fire and to take a 3% QA over 4%WSD.
QA effectiveness varies a lot for WS damage.
Generally speaking it's less effective when:
- WS has huge fTP on first hit, like for example Savage Blade at 2500TP+ with WSD has 20+ fTP on main hit, making 3 fTP from QA less impactful
- You have not enough acc on additional hits. For example Fudo/Torcleaver sets can sometimes have problem with that
- WS is one hit, so only one chance to proc, but this rule is not always that simple. There are 1hit WSs that have rather low fTP on that hit and they are boosted with their own WS damage, like for example Catastrophe. QA proc on Catastrophe has only one chance to proc, but adds a lot of damage.
- You have AM3 on mythic active and/or lots of multihit in WS set already. QA will just have diminishing returns then.
I would say it can't be judged in general. It requires case by case analysis for each WS+job+set scenario.
