MVC 4, Keeping Convention over Configuration

I’ve found myself adding several actions methods to a controller, repeating the action method type, like for example, having more than one Index method at the controller. Of course, I add something like ProcessAIndex, ProcessBIndex, etc.

I believe that may not be according to MVC principle of convention over configuration, so think I should have more controllers. I also think I can use Areas to mitigate controllers proliferation I’ll get. Will investigate more and will keep updated.
