Sadima's Touch vs. Aurseize

Think iiq don't work on maps anymore thus iir cause iiq would be pointless if it does nothing Kappa

Afaik IIQ still works in maps, but there are diminishing returns we know nothing about.
A prevention against legacies.

I know it works for sure, equipped with around 80 IIQ on a standard MF char. What else I've noticed is, increased quantity doesn't reflect on much higher amount of high orb drops, nor any kind of excessive number of item drops. I've been using this setup only because I play strictly solo (and it helps, it's true), but lately started to lessen IIQ and trade it for IIR, find it more rewarding.

What I've also noticed it's better to roll better maps and/or play in a party with high IIR, instead of wasting slots for dedicated IIQ items.

They wanted to kill IQ and heavy MFing in general and somehow succeeded.

The problem I can see is they are not replacing their outdated MF system with anything better, combined with reworked affix system, but simply increasing the time needed to acquire valuable drops.
