I don't think I would romance him but I certainly enjoyed the frenemies connection he can have with Tav. I wanted to see more of him!
The alliance with him should have been more long-lasting and meaningful. Would have been cool if he was a quest giver or even a companion (evil route doesn't have enough of them) and you had choices how to impact the city, for example helping out the Steel Watch, coming up with ideas for newspaper propaganda, sending Wyll to the Iron Throne as a prisoner so he can keep his father company, etc.
He fucked up Karlach's life, this is enough to put him on the very bottom of my trash-tier list.
He did my Tav a favour. Karlach seems to be designed as a cannon fodder character and she even admits she'd pick tentacles over a poison. It was super easy, barely an inconvenience
to choose who would get to turn into a squid after helping Bae'zel free Orpheus.
