There were 6 main cast members of Suits in season 1 with equal billing and they were all present today at the reading. They are an ensemble cast. ... All of the show's promotions starting season 1 has included all 6 of the ensemble. The only difference with season 7 are the career changes of Rachel Zane (Meghan's character) & Mike (Patrick J Adam) and that is something that both characters have been working towards since season 1, nothing to do with the personal lives of the actors. Since Gina Torres left the ensemble went down to 5. A quick Google search easily shows the cast ensemble pictures used for promoting through the 7 years, for those who are not familiar and think that there was not equal billing with the cast.
Exactly.

Acting is a profession, and when actors are able to land a great role on a tv series that becomes successful, and if they are surrounded by top-notch producers, writers, crew and fellow cast members, it's a lucky thing. On a show where everyone is professional and understands what they are there for, things run smoothly and everyone supports everyone else. Of course, many of the actors develop close friendships with crew & cast members off-camera, and there is joking around on set in order to loosen things up with the long hours they put in. (
Suits often films at night.)
Most importantly, the show is their bread and butter, and there's no playing around with their respective livelihoods. There's also no interfering into nor exploiting the personal lives of co-workers.
Suits is a high class show with high class people involved from top to bottom.
Probably it has been more of a headache for the producers and crew having to deal with the OTT interest in one of their actors, which has nothing to do with their work or her work on the show. Not everyone who has become interested in Meghan is actually tuning into the show on a regular basis I'll bet. If there are more people watching
Suits who are truly interested in the show itself, they are probably viewing the DVDs of earlier seasons, and that's hard to quantify unless there's an upswing in people buying the DVDs rather than renting or borrowing from libraries.
Sure there might be some bonus for all involved due to the increased interest and attention being paid to the show because of Meghan's involvement. However, I am not sure whether it has actually been quantified how much Meghan's popularity may have spiked the ratings, if at all. Reportedly, the ratings actually decreased during the sixth season as a direct result of Gina Torres deciding to leave the show after the fifth season in order to move back to L.A. to spend more time with her husband, actor Laurence Fishburne. Acting has its upsides but also some huge downsides. It's been reported that Torres will be working on a spin-off series (about her character Jessica Pearson) that she can work on from her home base in L.A.
Possibly, a real and longer term interest in
Suits could develop with people tuning in to see Meghan and becoming hooked on the plot and the characters. But if the novelty for people who aren't already fans is just Meghan, then only seasons 1-7 will be of interest to them should Meghan not continue. And if the show goes on for an 8th season with Meghan no longer a cast member, that may affect ratings simply because there are people who love her character and follow the show because of her character, and not because of who Meghan Markle is dating in her private life.
When, for some reason, you're thrust into the limelight because of a personal relationship, it can be all intrusive, annoying and totally throw a person off balance.
