I mean if it's working I can't see how anyone can call it wrong. My first play through I did mostly strong and quick attacks along with signs. It was a challenge but I still rolled through the game..
It just depends on what kind of experience you want. For my second play through I wanted a more skyrim-like experience were I could just wreck anyone i came across with very little regard.
I know somewere I saw a viper build built on quick attacks, some alchemy, and the viper armour. Maybe go check that out.
