As a general rule, fusing armors (almost?) never gives you anything worth having. Use fusion stones only to create cheap(ish) 50ep armors from basic elements to level up your 3*+ and 4*+ armors at the higher levels (at least level 50 onwards unless you have a ton of spare fusion stones).
There are threads about the most efficient ways to level up armors, in time and game money.
