I really want dual Daggers to be more useful for Rogue, it's a more iconic type of weapons for the archetype.
Dual wielding Rapiers just feels really weird to me.
I think that Rapiers thematically works well with Arcane Tricksters for example as a one-hand Rapier and the other hand free for spells, but with Rogue it just feels strange.
I wish Larian would buff Daggers or something, otherwise I hope modders will fix it.
I agree about twin daggers as a more useful option (not just for Rogues in my view), but the danger has always been weapon-creep where suddenly twinned daggers are twinned shortswords and then twinned 'longswords'/arming swords.
Twin rapiers was a fighting style taught in the C16th. Not terribly popular from what we can tell, but it was certainly a developed style. I'm against using it as a standard combo, but allowing it on a Feat chain seems appropriate.
