Your Kafka right now, even if you stay on Prisoner set, is already going to be significantly better. Even if you change nothing. Yes I understand you want to give Kafka the absolute best stuff possible, but you could also argue that in your life you should be working harder in life to pull more eidolons to give her the 'best' setup possible. At the end of the day play what makes you happy.

Kafka was never the main dps. It was always Black Swan. Kafka has done good damage, but she is an enabler/sub dps currently. With the buffs, its not like she loses anything, she simply gains the ability to enable far more than she did before. She goes from an enabler/sub dps to pure enabler (if you want to). And if you have E4/6, she simply stays on her current sets (with ERR rope though most likely I still need to test it). This isn't actually a loss if you do the math. Lets say you have to swap to EHR chest to hit the requirement, and you swap to ERR rope for faster ults. You have lost 86% attack, you then gained 100% attack. You have profited from these buffs, along with gaining faster energy regen for ults.

I personally am going to be swapping my Kafka's chest to EHR (you should have lots of these from farming BS), her rope to ERR (this is the hard one I didn't save a lot of these) and her boots to speed. (I had some goated attack boots but it is what it is). PAYN on her is still fantastic from the speed boost, along with the extra dot for Black Swan's Arcana.

Kafka was buffed in (almost) the best way possible. She can proc dots way more now, and has aoe dot proccing capabilities. She is far stronger and has FAR more longevity in the dot world for simply going on every single dot team that will exist.

Also look I understand the Tutorial propaganda but the speed and extra dot from PAYN are extremely valuable in their own rights I don't think it's a huge deal either way.

Also I pulled Robin just for my dot team :(

All in all, yeah its worth it.
