Same here! I was thirteen, and while I came to like Picard by season two, I liked Riker a lot more. I also felt the show lost the sense of adventure and fun of the first two seasons after Riker continued passing up command offers and decided to stay put on the Enterprise.
Riker reverting to commander after achieving his dream of being captain ultimately killed the character. That was what we were shown he was gunning for and what he'd given up Troi and so much else for. Instead, he decides to stay on the Enterprise with Picard and becomes a miserable character who was a shadow of his former self.
I think I might have been the one to suggest that Riker stay in command while Picard get treatment, though it's certainly not an innovative idea. I thought it would have revitalized the show to have Troi and Beverly stay on Earth to aid in Picard's treatment while the Enterprise went back out with Riker. I know she wasn't interested, but I'd have loved to see Dr. Pulaski return. Instead, Selar could have become CMO (Suzie Plakson more than deserved to become a regular or semi-regular) or a new doctor could have come aboard with a new counselor.
Data could have been promoted to XO and Worf could have gone to Ops and position of second officer, with a new security chief joining.
Patrick Stewart often lamented not getting as much theatre time as he liked during production, so this could have worked out. If/when Picard returns as captain, Riker could have gone off to a new ship but still appeared occasionally, leaving Frakes to direct episodes when Riker wasn't involved.
