The life changing decisions by some characters

Idk if this has been pointed out already but I hated the way Jessica, Mike and Rachel all basically left the show on like an impulsive decision which is totally the opposite of their characters as they knew the firm was another family to them. Like Jessica for example, one pro bono case made you leave the firm and City you spent decades trying to build up to where you got????? Mike and Rachel’s exit aswell was so rushed even though this was more plausible than Jessica’s exit. Like they just uprooted their life to go work for a man that they barely knew? Idk man
