I prefer the UA playtest where the backgrounds were examples but players were free to create their own. Yes, I know this can be easily done at tables that prefer it. WotC should be encouraging player creativity, however.
The current backgrounds are all mundane and will mostly be chosen for mechanical benefits, and frankly should be. Some of the logical backgrounds are very poor choices. Why take the musician background for a bard? It'll just double up on what a player already has. Same with acolyte for cleric or guide for druid. This seems like easy traps for new players to fall into, yet we are told a curated list is good for newbies. Not this list in particular.
