Personally I feel the D&D flavor of druid is kind of played out - for me. It's overly niche and wasn't that good to begin with. Hippies, granola, and polymorphing into D - B tier monsters isn't THAT interesting.

Now something like a miyazaki nature force. That might be cool. Give an aesthetic that's more menacing, strange and unearthly, and competitive with arcane power. Then I'd understand dedicating your life to this.
