Kul Tirans have some of the best druid forms, hands down. The wicker creature asthetic is top notch and I love the forms, but I don’t want to play a Kul Tiran. A lot of people don’t want to play kul tirans but a lot of people like their druid forms.
Give druids a quest that lets them learn the druid forms of the other races. Cenarion Circle would absolutely be open to sharing knowledge with other druids, as it can better safeguard the emerald dream and azeroth.
