Druids will get free Healing Word thoI didn't get that read from Jeremy, it read more as "this is a playtest, nothing is set in stone".
Assuming other prepared spellcasting classes will follow the same prepared spells = spell slots, it is amusing that the Ranger will have more spells available to it than its Druid cousin, since Rangers get 2 cantrips, 2 1st level spells and Hunter's Mark.
