The spell is supposed to have a verbal component and for a good reason, both thematically and mechanically. Thematically because you have, of course, "to guide" yourself or someone else (with a speech presumably); mechanically beacause it shouldn't allow a character to perma-add 1d4 to his/her check during social interaction, at least without repercussions.
I honestly think Guidance should trigger some hostile reaction if used in rolls against NPCs you are actively engaged with and, if this is too complicated to implement, remove the option at all and leave it for the other interactions requiring ability checks.
Otherwise, you are just going to have a permanent +1d4 to your ability checks, which is really too strong in my opinion ^^'
Am I the only one thinking it?
