Currently tree harvesting feels sluggish and tedious, as does taking care of them. Animal and garden interactions are much faster for the reward amounts you receive, and also give far superior iMG. It would be nice if an upgrade card came out to slash the time to Pet, Harvest, and Water a tree to 1 second. Maybe you could call it Low-Hanging Expertise, or split that into 3 separate cards (one for each action).
Barnacle Pods, Jellisacs, and Gardens all received similar upgrades. It's the Tree's turn.
