A Way To Fix League (The hearthstone way)

I have been playing hearthstone for almost as long as I have been playing league, but the difference is that the changes made in league are making it difficult for me to play the game anymore but my love for hearthstone still exists. But why is that? So after brainstorming for 30 secs I realized how hearthstone is balancing between their new 'innovations' for HTC championships along with the gameplay that the veteran love with wild. So I had been thinking that why can not league create its own 'wild'. A system that brings out the old s4(or any that the majority demands) and then have a standard gameplay system where they implement all the new updates for their flashy lcs plays? This way both the player base and the competitive play wont be damaged and everyone gets to be happy.
