Are you talking about Elemental? Elementalist build for Enhance is a combination of Lightning and Fire given that your top 3 damage contributions are Fire, Lightning, and Elemental Damage in single target. Ice also plays a large part as well. In keys, Nature damage from Lightning Bolt, Chain Lighting, and Crash Lighting make the largest portion of your damage profile followed by Fire damage and then Ice damage playing Lashing Flames.
Literally my choice to play enhance had nothing to do with lore, theme, or some NPC. It (Elementalist build in particular) looked like it had a cool rotation, neat utility in raid and M+, and fun gameplay expression IMO so I decided to swap to it for DF. And I have been a happy camper ever since.
