is TEC in 1.03 become extremely powerful.
Due to the way the black market functions at the moment, credits are extremely powerful in 1.03 and the TEC get earlier access to trade ports (as well as trade-boosting research) than the other factions. They also get research that improves black market trade rates.
They aren't unstoppable but they do have a fairly large economic advantage.
I heard the vasari's returning armada got nerfed in 1.03 and it is only effective in late game. Is that true??
As far as I know, nothing has happened to Returning Armada. People just don't talk about it as much lately because there's really not much to say that hasn't already been said.
