Thanks for the info.
Ok, you guys must be min/maxing something.  All I know is that I generally start out with about 10 AP and each turn I get about 6 or 7 back.  Like I said I don't use Lone Wolf (why would I?) since I like having companions.  So for me I suppose I would start each turn with a full AP bar, that's nice and might get me an extra attack (don't use rogues).  That hardly seems worth the HP hit.
Generally I don't min/max when I role-play as I like it to feel more natural and not forced into some demi-god build every time I play, so maybe this talent just isn't for me for those reasons alone.
