Han Solo, General Leia, and Master Skywalker are not losers.
Han went from a hero and General in the Rebellion, and being ready for a committed relationship with Leia to going back to smuggling, abandoning his wife and son, and then got stabbed go death by his son in a last ditch effort to save him. Luke went from being the last Jedi, who redeemed his father to falling from his faith completely, just wanting to die, abandoning his family, friends, and the galaxy as a whole, only to die from Force exhaustion in a last ditch effort to save the handful of remaining rebels. Leia went from being one of the leaders of the Rebel Alliance and of the New Republic, while starting a family to being a general of a band of rebels that can fit in the Millenium Falcon having lost her husband and son. In the context of where they were at the end of the OT, each of the big three lost in a major way, and worst of all after building a powerful friendship over the course of three films would not share a single scene together in the new trilogy with Luke only becoming aware of the death of his best friend after the fact.
