No. they didn't. If you don't understand the difference between what WOTC gave and what the OP wanted, sit under a tree and contemplate it.
Level 16, daily, close burst 2, all allies may spend a surge or make a save. Compare to a Warlord at level 16, encounter, close burst 5, all allies may spend a surge and get +2 defenses. Or a Cleric, level 10 (they don't even GET a level 16 heal), daily, close burst 5, all allies regain as though they spent a surge, plus Charisma. Looks to me like a weaker version of a leader's heal, straight up.
Again, what is being asked for is a considerably more significant dip into a leader's abilities, for no additional cost. To do this, the entire class would need to be retooled, taking out something to put that kind of healing back in. To simply add it for no extra cost is unbalanced. If Silverblade wishes to have that kind of healing for the Druid again, there is no reasonable way to do it without removing an equally significantly set of abilities from the class, or, one final time, the class will be overpowered.
