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

Are there any current weapon foci that works for the Druid Wildshape such as unarmed strike? If not, could one for creature weapons be added for those Druids that actually want to melee?

Not long ago there was a discussion as to if Dragon Druid was 'too powerful' so I doubt that they will be given anything 'extra' in the near future. That said I can't imagine a shifter druid having any issues with melee, they are pretty strong melee attackers with solid AC...

Weapon focus unarmed works.

For bear warrior's rage, wild shape (and polymorph self/shapechange?), the unarmed weapon focus, unarmed weapon spec, unarmed improved critical, and unarmed power critical feats translate into the appropriate creature weapon feats.
