he tool was updated leading into Season 13 for Druid, Sorc, Necromancer, Barbarian, and the new Warlock. Spirit Born and Rogue were still missing at time of filming: Rob estimated those would be up within a few hours. Take "a few hours" with the same grain of salt you apply to everything else pre-launch.
Current completeness: approximately 50–60%. Most skill trees are partially populated. End-nodes and some upgrade stats are unknown because Blizzard hasn't shown them. You can still put points in: the tool accepts input even on nodes it doesn't fully know. What those nodes actually do remains Blizzard's secret for now.
The interface is straightforward enough that explaining it feels condescending. Here it is anyway, because someone will ask.
The planner will be updated on launch night: Rob's stated goal is to have the remaining nodes filled within a few hours of Season 13 going live. Until then, any build you construct is a draft. A well-reasoned draft is still useful. A build built entirely around unknown end-nodes is a prayer, not a plan.
The Druid skill tree has a structure no other class shares: separate skill branches for werewolf form and human form, in addition to the shared nodes. When you zoom out on the Druid tree in the planner, you will see these additional branches extending outward. They are not a visual glitch. They are genuinely separate skill sets that only apply in their respective transformation states.
This means a Druid build requires a decision most classes do not have to make: which form are you actually playing, and how many points are you investing in transformation-specific nodes versus the shared baseline. The planner supports this. It does not make the decision for you. That remains your problem.
The bottom nodes on every class tree: the ones with the most transformative effects, the ones build guides will revolve around: are locked behind owning the Lord of Hatred expansion. The planner displays them. You can see them. You cannot use them without the expansion, and Blizzard confirmed this in their pre-launch blog post.
Do not build around bottom nodes if you do not own the expansion. The planner will happily let you assign points to nodes you cannot access in-game. It is a planning tool, not a gatekeeper. The gatekeeper is Blizzard's payment processor.
Yes, cautiously. The node exists and will function. What it does exactly remains unknown until launch data confirms it.
You can see them and click them in the planner. The game itself will not let you use them. Two different systems.
