I'm also not so happy with the changes. Main problem is the hugh amount of effort cards in PvP. That makes the game less strategic and more random. Before the changes I could calculate with my effort. Now almost every attack raises effort. That makes planning almost impossible. That's a shame.
And bringing just one wolf as a scout - ah, come on. That was the scout's strength! The scout cannot jump or teleport over other unites. At least the wolfs were a possibility to get over the ranks of the enemies.
So, for me: I liked the game a lot more before the update. I'm not going to stop playing, but I'm not that enthusiastic as I was before.
