Should Alexander hard drop highest item level gear?

[Waliel]

False. If you really think i110 non melded gear is better than anything i130, you need to research stat weights.

As it happens to be that is exactly the case for caster gloves for BLM.

Evenstar Gloves i110: 34,908 effective INT
Augmented Ironworks Gloves i130: 34,444 effective INT

The gloves are absolutely horrendous DPS wise.

You talked about the story only needing i90. Fabulous, do Shiva EX with i90...wait to even do the DF of it you need i95. Though even with i95 you are going to be hard pressed to down her unless you are in a premade.

Shiva EX is not story. HM is 80, Steps and Chrysalis is 90.
