About the 1 IP gifts. I do see this as a bug, because you get something for nothing. Imagine if you could hit control-I and improve relations with all the AIs, without penalty to his civilization or to his score. If some player found that such a cheat code was active, it would universally be considered a bug. Gifting single influence points is completely equivalent to this--there is absolutely no difference from a gameplay standpoint, not that I can see anyway.
Gameplay is about tradeoffs and weighing the benefits and costs of various options. There is, from a practical standpoint, zero cost to giving a 1 IP gift. Why would you ever *not* give a 1 IP gift?
