I can understand if you take things personally, after all you designed most of it (not the harbors in this case, but whatever). But you have to understand that with you having the final say on things there just isn't a counter for you saying "The current UA is fine", all I can do at that point is bringing up reasons why it isn't fine, because you're locked the alternatives down.
I don't take it personally- I've been a teacher (and an internet-goer) for a long enough time that it takes a lot to get under my skin. I'm trying to help you out here. You'll get a lot less blowback from myself and others if you approach discussions from a 'positives' perspective. I'm a firm believer in the argument that proper brainstorming can only happen in a constructive environment (which is why I'm very fast to shut down negativity in the subforum).
First of all I still do believe that the Indonesian 'no isolation' thing could be stolen, they are really powerful anyways and really don't need that effect.
Other than that, what are the key points of Carthage? Naval power, expansion and Trade? With the UB covering the trade aspect and the UU sorta covering the Naval power aspect the theme of the UA should probably be expansion (probably with a dash of Naval power to spice it up), any ideas?
Indonesia's bonus is pretty thematic for their ICS spice love. It is quite useful.
Here's the deal:
If Dido is going to keep her coastal/ocean theme, connectivity is fairly unique (none of the other naval civs have instant connections) and the harbor is a no-brainer for achieving this. If she isn't going to have this, then the question becomes "what role does Carthage have in the world?" Right now she's an early-expander/conqueror that transitions into a mid-game trade giant. By the late game - hopefully- her bonuses or war/trade exploits have helped her secure enough wonders to stay relevant in the late-game. Without harbors, this becomes harder. Without the extra gold, it becomes even harder.
