I tried a rogue that I built into heavy crossbows and line-holding while also having Ass Orion, there are definitely times I feel that it was redundant/wasteful (such as skill checks) but it pays off during stealth fights.

Having 2 characters that can move, enter stealth, and sneak attack in the same turn is extremely powerful.

[SPOILERS BELOW] Beat the cenobite doctor and the toll house lady back to back using this at lvl6, neither bosses got any attacks off on my guys. Idk if this is supposed to be impressive or anything, but In both cases I used both rouges to exploit the bosses AI, although admittedly the toll house fight was clearly designed for stealth.
