Number Crunching:

Cost per level = Fusion Cost + Armor Cost. You can optimize and reduce costs, but this gives an idea of when things start changing.

I have lower costs per level with Silver (10EP) armor to lv15 and Snakeskin (24EP) armor to lv60 and 2* (50EP) armor over lv60. (Not Lv20 and Lv40 as in original post -- The numbers say Lv15 and Lv60)

If you have wind (Unmatched for Snakeskin) -- Atlantean Avenger (24EP) @ 6000 is slightly less expensive than Snakeskin (20EP) over lv49. I found no point where Spirit -- (Chimera @ 12000) or Fire -- (Living Flame @ 15000) were better than unmatched Snakeskin.

Fusing 4x bronze into a silver and using Lv6 Silver (15EP) costs less than using raw Silver (10EP) when over Lv28.

Lv20 Silver armor (29EP) -- made by 1 silver fused with 4x bronze (24EP) + 4x silver (+40EP -- 64EP) + 4x silver (+40EP -- 104EP) is only 5% more expensive than matched snakeskin at high levels and up to 13% less expensive than unmatched snakeskin over lv60.
