I've been playing in a beta of another game similar to Divinity in some ways and they had this as well. You can set two weapon sets and hot swap between during turn based combat. I really love that idea and I think it would go a long way in making rogues more viable.

I always ran into the problem of wanting to range some targets to soften them up before going in melee, but the fumbling around in the inventory screen causes an unwanted lull
