Although, maybe it just seems that way to me as a Forest player. For me, the overpowered dragon is a tough, but manageable opponent; thanks to wards, healing, and Lilith, I can actually hold out until the round(s) when I can take out a huge amount of its HP in one go, if not all 20. Sometimes I even rejoiced when the enemy dealt 11-13 damage to me and left its face unprotected, so that on the next turn it would receive a massive amount of damage from cockroach mandibles. I'll venture to suggest that with this nerf, my chances against the dragon will increase slightly, but not significantly.
But against Shadow, things are still just as bleak. I hope the nerf to Catacombs will have more of an impact than I currently see (yeah, right. Before it was 1-drop - 2-drop - Catacombs, now it will be 1-drop - 2-drop - Chimera - trade the Chimera - Catacombs), at least it will compete with Orph, and the Shadow curve will rise, which could be a good sign. Although, I would still prefer to simply make it pay in Shadow energy for this effect, and pay a good amount. And I really want to increase Hector's cost in Shadow energy or PP, or both, because he is just ridiculously good; yesterday in the arena, I drew a terrible hand and Hector, and both of my wins were only thanks to him. Although, there is hope that with the 4-PP Catacombs, Shadow energy will accumulate more slowly, and you will also need to spend it on Breath and other interesting things. But I don't believe that aggro/midrange Shadow will suffer that much. It reminded me of the story with Dash, when they increased the cost of Piercing Rune by 1 PP for the same reason (a significant difference in win rates between the first and second), but Dash didn't feel it and continued to dominate everyone. On the other hand, now it is in the worst possible state, so we are waiting for the next expansion.
I hope they break Forest, and I will have time to dominate everyone to my heart's content before the nerfs, because I just started to enjoy playing with the cockroaches, and they were nerfed to the point of being unplayable :(
