I usually play 2-3 games a week and I don't feel balance issues much. But when I watch high level games on twitch, usually people complain about certain units which I feel is a bit premature. For example, people complain about Berbers camel archers, but you need to get a castle up to produce them which is gives a lot of time for the opponent to rush. Definitely certain civs are better in certain maps, but that is supposed to be case. And most discussions seem to be based on the setting 1v1 arabia which I feel is not ideal. People have a right to complain about units being OP but the balance changes should definitely put more importance to the overall game and not just some particular settings.
