update - Atomic Emu, Pet Conjurer - Callagadra Facetank Edition is back on the list as being 100% viable in 1.2 (in terms of tanky laziness), courtesy of testing by @Snazzblaster 
I should add that stuff like SR 140 is probably not going to happen in 1.2 anymore, but that we will see once the patch goes live :3
Hey Maya! Great to see you!
I’m coming back from a hiatus and I’m looking to make a fresh start. I noticed where you gave props to your Ishtar build as being very viable in the upcoming patch. I’ve always played your Fluffy Squishy…what’s your current recommendation? Is Fluffy still viable…I’m not 100% sure what’s changing.
Thanks!
Welcome back 
Regarding the current status of my builds in 1.2, they all seem to be viable.
I was mostly concerned about the new mechanics and how my builds might be affected. Since I play on GoG, I am not able to participate in the playtest (only available to steam users).
So, I was going with a relatively safe choice with Ishtar since Reap Spirit is pretty much immortal and the build itself is rather tanky. But, since making that post, people have been helping me test out my builds and it seems that they all perform pretty much same as they always did.
So, essentially nothing to worry about and Fluffy Squishy is 100% viable.
The change I was concerned for was mostly the Sunder mechanic, which is a debuff that bosses apply with some attacks and makes you take more damage for its duration.
I was worried that pets might die a lot more or that the tankiness of my builds might suffer too much, forcing me to change them into more DPS focused.
But it seems that with all the other changes happening as well, everything evens out and balances things.
PDF Guide updated. Changed some things in light of the upcoming update and expansions.
most notably - Will O Wisp is longer in there since the build has proven to be too unreliable despite everything I tried.
A new budget pet build added to the OP (will update the pdf some other time)
