Anything legendary or below should fuse into a random armor (elements mean nothing anymore) exactly 1 tier up. That's why with the new fusion system doing fuses on anything below legendary is probably a big waste of gold, since if you look at the table at Armor Enhancement, the least bad now is investing 2x 10 EP to get a random 24 or 50 EP. Anything else is breakeven or loss on invested EP vs resulting EP. Only legendary+legendary->epic, epic+epic->epic or bad DF, DF+DF-> bad or good DF are kind of worth it to try and get good DF. (plus of course trying to fuse old SF for a chance up to season 5 SF; see also Fusion)
