Hey, I have not run this custom with a healing core module. I’ve been running that custom with ascension as the core. You might want to look into that seeing as how ascension gave you some good results. Customs are really good for hitting sticking points and it sounds like you’ve identified a few.
I haven’t done any direct healing with a single title in a looooooong time. I’ve since identified I “heal” better by outgrowing vs direct healing targeting. So before zp I had a variety of healing modules in my custom. Now I run a more lean custom with minimal healing.
I think this comes down to how I’ve coped with things in the past. I’ve always been avoidant, without enough forward momentum and change I can get stuck in the past because my mind also has a tendency to operate like a broken record at times. Main point being a lot of this stuff varies person to person and sometimes you have to experiment a bit.
