So do people not want the titans/atlanteans in AOM Retold?

I keep seeing people say how they hope AOM retold only sticks to the original 3 civs. I can understand those who want to exclude the Chinese, but why the titans expansion too?

Is it because the Atlanteans are a fictional civ that are basically just the Greeks part 2/ the Roman's with a weird paint job?

Is it because people think they're unbalanced?

I also see people don't want titans in the game.
