It's an ok build. But it has more improvement.

If want tanking and offensive unit build, replace courage aegis to RC5 or RC6 Harbinger sphere for 100% atk/def, since you had put 50% hp on him, the side effect sphere -40% hp can cover it.

RC6 sphere has more powerful effect, has at least 4-5 effect, but it take lots of works to farm materials from raid, and it's free to craft. Here's one of the RC6 sphere Lustful Torment effect:

100% boost to Atk, Def, boosts Atk and Def by 50% relative to max HP, 25% chance 15% damage reduction, 70% boost to Spark damage, 70% critical hit damage, 100% BB Atk. Side effect is reduce -40% HP.
