I think this second season would be much less popular because the story arcs are taking a transitional turn to build up the world and audiences who take delight in that are minority, at least from what I saw on the Internet. From the others' perspective, the anime ''wasted'' 4 episodes to watch boring lizards...The exciting, indulging and pandering action where Ains and co stomp everyone is absent and the stars of the show, Nazarick team, have little screen time to interact with each other. The new and supporting characters like Climb are hardly stellar to replace, IMO.
So this second season is the kind of necessary story arcs but not great and interesting.
25th April is when the first volume disc is released so we will have to wait until then to know how well it will do. First season is a 12k/volume series (generally speaking you need about 6k-7k to get back the cost) which is very good so I venture this season to be around 6k/vol.
