Loved my steam controller, just like all the best stuff it took some configuration to get it perfect, but once it was set up it was the best controller. I am firmly a fan of configuring my stuff to work the way I want to use it, not adapting to how someone else thinks I may use something.
If it makes you feel better, it will never be the same as it was when you first played. Every time there is a xpac that looks interesting I have tried and failed to get that feeling back. It devolves very quickly into feeling like a job again.
