Pretty much. I'm doing the same debate ;_; I'm edging towards Nightseeker with a back-row Dancer. The chase setup won't take off for awhile and, by the time it does, it'll be quite some time in the game. Might as well go with the better random encounter default setup (L/F/N | D/R) and swap as necessary for FoEs.
Edit: Plus, Status Effect -> Bonus Damage combo from Nightseeker seems more viable than Sniper's setup anyway.
I also have no idea if keeping my Fortress is even a long-term thing, really, but that's a matter for late game planning, I suppose.
