We could fight her brood of spiders and probably also orcs seeing as she's a corrupt Maia like Sauron is- and one tough enough (after she consumes the Two Trees) to give Melkor himself a run for his money. Also after the Balors drive her off she's never heard from again, do you get a lot more creative freedom there. As a bonus we might even get to ally with Melkor's Balor Spec Ops killsquad against a common foe if we play our cards right which would be pretty sweet.

Plus, there's all the fun of fighting a giant spider that *steals light to make webs.*
