I haven't done much searching on the topic of Attribute scores and if we will get a chance to change them come mod 16 so forgive me if I am wrong here.
But for the love of Selune please, oh please allow us to reroll our attributes. If the attribute scores are changed and impact the character differently. For example if intelligence is more helpful to a cleric in mod 16 but when we made the character wisdom was chosen an we had intelligence as the lowest attribute then the character is no longer ideal to the new mod. So please, please, please give us attribute reroll.
