Is this really all of the changes? If it is then it is, I'm not complaining but I suspect that there is a lot more not mentioned as could be said about just about any software. I also respect the fact that discovery is part of the excitement of new content but I have to believe that with so many pvp bugs, AI oddities and thousands of requests for changes to game mechanics that there must have been more changes that only required changing a few variables that weren't documented.
Also, I think the change to sundial without some sort of compensation was a big mistake. No matter what adjustments people make to their FG farm decks, our win rate will significantly drop. The nice thing about sundial was that it sometimes bought us the time to draw the cards we needed to stand up to the rate that the FG's draw cards and gain quanta. Sundial was not an ideal card for pvp as so many other decks are better than rainbow decks. Sundial got nerfed because of arrogant and elitist discussions about the balance of sundial ("I'm so good, I'm going to ask for sundial to be nerfed because I'm so good that I can win 80% of my games against FGs without it" type of attitude). Was it overpowered? In general yes but it was critical against FGs. Aagain it bought time. Even against decks like Miracle and Fire Queen I am losing from time to time because I don't have that time. I'll take specific strategy to the FG forum but the new cards and new rules did not compensate for the significant reduction that everyone will take to their win rate.
Win rates will go down against FGs and no one wants to lose as much as they will. It's just not as fun. Those of us who are in the T50 will hit a decent bump in the road over this but imagine those who are coming up, are much more casual and don't have the resources to build 10 of every fully upgraded deck imaginable. You will lose a good amount of your player base. And to my fellow veteran players, keep in mind that this game isn't just about us.
I personally could care less if Sundial stays the way it is or not but either nerf the FGs, boost other defensive cards, whatever. Mark my words, people will lose interest when they lose as much as they will. Boosting our HP by 50 and giving our creatures some extra attacks will not make up for the fact that the FGs can slaughter us in a handful of turns even when we have a very decent draw.
