I went mid-range with my romance - snarky but not insulting.
SPOILERS!!!
And, I am hoping that there will be 'more' for Arath, such as cross-modding (which would be great, esp. regarding Salaufien). My only complaint (not really a complaint...) is that the romance and such progressed very quickly. Maybe I had my timer set too high with the 'fix' mod; I dunno and can't recall how I installed. But, I would have loved the whole 'broken up' thing to have lasted until they got out of the Underdark. Seemed they were broken up at Spellhold, and then back together half-way through UD. Again, could have been an issue on my part with how I set the interjections timer.
But, cross-modding ... yeah, would be super cool
