So right now it looks like College of Lore specifically gives Arcana, Intimidate, and Sleight of Hand. Is this a bug, is there a plan to change this so that people can pick their College of Lore proficiencies, or is this how it is intended to be?
You are supposed to be able to pick "wild-card" spells from ANY other class.
That's for spells later on, though. (And all bards get those, but Lore bards get more).
I agree about the skills, though. Especially if a bard already has one or more of those skills, since they don't get the chance to choose a replacement.
I filed a bug report and was told this is a known issue that will be fixed in a future patch.
