The Developers do listen and care about Community feedback. For example, in regards for the Eniripsa, I feel that you're not being entirely fair: the healing potentials of some of the spells have been increased yesterday, and I for one have yet to see the new numbers in action.
But working with that feedback is not always simple. You have seen what happened with the Prestige Levels and Spell Variants: we listened to your feedback, and went right back to the drawing board. Now it's gonna be months before it is ready to be share with you again.
We are trying to do better, we really are, and we need you to be patient with us while we figure out how. The Gamakna is, we hope, a step in the right direction. Other than that, please do keep giving us feedback. It helps.
Also, I would be remiss if I didn't stand up for Izmar: it's true she isn't interacting much with you these days. She is in fact working behind the scenes to make sure I can interact with you as much as I do, and trying to make the whole "line of communication with the Developers" thing easier and more efficient.
