The cause to my possible leaving of this game

I do not understand why cure and sacrifice are now no longer AOE. This is ridiculous and makes for constant wipes in big parties. I undertook my first instanced raid last night and my party wiped three times from relatively weak enemies. They also removed siphon mp from AOE. This means they made it even harder to get mp. This is all ridiculous and I can not believe they put this in. I am willing to keep trying this new update out, but it seems as though this game is almost forcing me to solo. I have been with this game since the beginning, and have never quit. This may be the thing that drives me away. I understand that Con's have an AOE cure, but I prefer to be a THM. I hope they fix the cure issue quick and fast, or I am afraid I will have to shut off this game until they do. Here's hoping that the dev's read this and other peoples opinions on the cure issue and fix it promptly!
