So you're saying that an AI that plays more like a human player than before is somehow deficient? We were told that the AIs in Civ V were meant to be trying to win. If that doesn't mean they'll take the same tactics as a human, who by definition will try anything, even "OOC" if order to win, then they've missed a beat. Basically, if you expect a human to do similarly in the same situation, then assuming that the AI will conform to certain expectations is a weakness on your behalf, and a strength on theirs. The only bad AI is in making decisions that are disadvantageous to the AI civ, not decisions that you feel are "unfair". If you can demonstrate that Gandhi clearly lessened his chances of winning by said strategy, then you have a point (and it wouldn't be the first AI weakness to surface). Otherwise, all's fair in love and Civ.
