Essence Reaver first item?

Hello folks,

I do currently enjoy playing Caitlyn a lot (next to Xayah my most played champ) and yesterday while I wasn't able to sleep, a thought struck my head. Essence Reaver Caitlyn.

I do always use onetricks.gg and dpm.lol for my item builds and as far as I can remember, I have not seen one of them suggesting Essence Reaver first.

I am a gold noob but in my head this sounds pretty legit, especially since I do tend to poke enemy's with e-q combo and an the sheen damage of Essence Reaver would add nice extra damage.

Has anyone of you every tried that or is this completely troll?
