Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

Bard is Proficiencies with Simple & Bard ~ (longsword, rapier, shortbow, and shortsword), longsword, rapier and shortsword are the bard weapons for melee, yet they get "Weapon of impact" but not "Keen", they shoud get keen also or atleast swap the "Weapon of impact" with "Keen", since that woud make sense taking the Bard melee weapons, it dont make sense they got keen for blunt weapons but not keen for slashing and piercing.

With greetings Tharnok

While true for specifically bard weapon don't forget that they also have access to the simple weapons and there are blunt weapons there such as club and mace.
