I cannot speak for epics, but its more a matter of gold then EP in regards to enhancing armors. In early levels (1-20) you can enhance using 4 armors for 600 to 12000 gold each time, in addition to armor crafting cost. This is pennies compared to the 60000 to 100000 cost per 4 armors up in the 50s and 60s. This means you want to get through the later levels as quickly as possible compared to the earlier ones to optimize gold.

While I cannot quote exactly how many EP it takes to level an armor by 1, I do know the number starts low and increases. I guess it is around 70 or so for the high lvl 30's and low 40s, and around 100 up until 60, then increases per level up to the max.

Also, guide is wrong: craftable 1* armor is 24 EP, not 25.
