I'm not sure that would really be a bad thing in a sense, but you would also be able to regain identity by being separate from the gestalt for a while then coming back to bring back your experiences and adding them to the greater whole.

You could likely also just chose not to fully sync with the entire collective since that would probably be way beyond a single brain anyway.

In most Sci-fi the collective as a whole form up a greater collective that is kind of the overmind, where as the individual members can still be fairly separate and make their own choices etc, and will only sync when they are in emotional distress or need advice or assistance beyond their own experiences
