Firstly the current system has been in the game like forever
Was it perfect?
No
But it is what people have been used to for years
Now if you replace it with a system that favours folks who do not do NiM gods(which i am sure we all agree is a good majority of folks who play this game) maybe you will not see sub loss
But you made it worse for a vast majority of the player base
If in doubt maybe do a ingame poll and ask people if they want this changes and i am sure you will get your answer
Now back to history lesson
Let me list games that failed to listen to their player base and changed it from a flawed system to an even more flawed system
Actually i only need to name one to make my point
Star wars galaxies
Of course this is not in the same magnitude as what happened but it follows the same principle
