Reading further into the interview, it mentions that they are releasing classes based on complexity, which is an understandable stance to take. Druid was complicated in both wildshape mechanics and immediate story relevance.
Still, this has super unfortunate implications. If you really want to take this at face value (and defining complexity as difficulty in coding), then the longer the reaction based classes get pushed back, the more you should expect that proper reactions won’t be a thing in this game.
