Well, all I can see is that I got attacked, almost lost my whole army to one unit and absolutely had no chance to punish/attack the opponent back since he retreated once his unit started droping dangerously low on HP.
There is no fun within. And since wealth is the main/only target (at least this is what I conlude from your answer, sir), if the game attracts more players, the endgame will look like mass royal dragons vs mass royal dragons.
So to sum up - my experience in online kingdom so far - produce units to farm wealth to mass dragons to leave the game 'cos of lack diversity and challenge. This apart from the bugs, that are different story looks like wrong concept to me.
I hope I am wrong about this all, but so far all this looks very true to me
