I don't mind legacies. I just think they need an overhaul from a design standpoint. They feel like they come off an assembly line and often they feel undercooked as characters. So I rather they skip the Robin/aqualad stage and start out with more unique names and setups.
Not really because most of Bruce's successors have their own reason to be Batman. Dick and Terry have revenge, Jean Paul has twisted faith and Jace has redemption. Damian is the only one with legacy as his reason.
