Druid’s fine, it has been near the top for most of Hearthstone, now it’s having a short period near the bottom. Priest, Shaman and recently Warrior all laugh at the Druid tears.
Nothing wrong with Druid being weak. I don’t hate Druid but it’s nice to have a change.
As for Naturalize and class identity, it used to be that Naturalize was unplayable. Druid had Mulch for a while and that was generally seen as a pretty bad card that some Druid decks ran out of necessity. Now the game has changed so Naturalize is good, I’ve no problem with it getting hof-ed on that basis but I am a bit sad because the Mill aspect of the card made it interesting.
As for Druid identity generally, it’s still got Ramp, Miracle and Token going on. I expect them to see support going forward. I also hope that there’s more Treant support, and that Druid still gets some Mill identity. There’s also ‘Big Druid’ and Beast.
Having Druid have weak single target removal, and weak aoe (Spreading Plague was a huge mistake imo), is fine, it gives the devs the opportunities to print strong, interesting cards in other areas. The mistake recently was making Druid have virtually no weaknesses.
