Also the only way you could "respect to beat persuasion check" is if you save scum.

You know, get into a conversation, see a Persuasion check needed, fail it, so reload, visit ship, respec, go do the conversation again, then respec after the conversation.

I could see them putting in something like a timer for Respec. Ie "only available every X hours" to avoid this issue. But frankly, its not really an issue.

If you know you're going to engage in a lot of conversation with people ... you have four characters. SPECIALIZE them. Like others have said.

Have one character max out his persuasion (Lizard / Red Prince gets a bonus). Voila, no worries about "respec to beat persuasion check!" just make sure that you do conversations with your 'face' man.
