(I still think it's funny and nonsensical that you can wield a Lance and dual wield it with a light weapon under our current version of the weapon. Only works if you're mounted, though, and is definitely better than the "dual wield TWO lances" from original 5e.)Wielding only one non-light weapon is sensible -- two rapiers never made sense, and the effective difference is ~1 hp damage per round.
