Anybody know a good World of Warcraft style movement / camera system on the Unity Asset Store?

As the title says, I'm looking to create a World of Warcraft style movement and camera system, for those unfamiliar with the game that means;

• Hold RMB to rotate the camera
• Use WASD for movement (and implement gamepad support)
• Movement in all directions
• Allow for zooming in

I can search for it on Unity Asset Store, but I would love to hear user reviews and recommendations.

I've already tried my hand on it but as a beginning programmer I got the functionality down but I have absolutely no idea how to improve it. What I've got now is terrible for gameplay. The camera rotation is jittery and unresponsive, even after tweaking several floats/ values.

I feel like it's more valuable for me to just get an asset that handles this stuff. If it's included in some kind of RPG bundle, even better. I found something by myself: Top Down RPG Toolkit - Beta | Game Toolkits | Unity Asset Store the issue with this however is that it requires a lot of tweaking in order for me to be able to make it how I want.
