In principle, the former fusion setups should still be the best ones regarless of upgraded slot or not. Although you currently can't trust the shown numbers when using the upgraded fusion slot. (Let's hope that at least the numbers shown in the regular slot are trustworthy.)

With the current bugged version (see here
) of the upgraded slot this might not matter. Those tests were only for a narrow fusion setup, but one explanation would be that the copied item only provides an increased success chance but is completely ignored when calculating the chances for the various fusion results. If this is the case in general then any FFFFE/EEEEL fusions in an upgraded slot (or also FFFEE/EEELL if the fodder item is copied) are in reality just FFFE/EEEL with improved success chance, which would still be okay (you save a Flawless/Epic and don't have to care about what is copied, but you also slightly higher chance to only get a fodder upgrade).
Ignoring the major issue that the numbers shown in the cauldron - our only source for making decisions about fusion setups - lie to us, this bug could be worked with, it has both advantages and disadvantages. Of course the problem is that we can't really be sure about the exact nature of the bug, so trying to work with what we think the bug is might just mess things up more. paradise, I am not even sure that the bug is related to the upgraded fusion slot. Maybe fusion calculations are messed up in general and were broken all along. (And as a player it's extremely tedious to properly test this.) There is also no guarantee that the devs will even tell us when they have fixed the bug (if they fix it at all), so it's hard to say what we can really rely on.
I have pretty much lost faith in the numbers shown in the cauldron. I mean it was always the case that we had to blindly trust that those client-side calculated numbers really match the server-side fusion calculation, but after seeing an instance where they don't, this basic trust is just gone for me. Not sure if this will ever be restored. I'll keep fusing but I'll try to avoid setups where the impact of this bug (or false reliance on this bug) could be really big.
