I will continue to play nothing but malzahar, and only 1 of two ways.
Neither of these are a bannable behavior in themselves and yet doing so will absolutely piss off your team.
Hell you might even win a few games despite having one arm tied behind your back.
The truth is refusing to capitulate and being an intolerant minority in the community actually works so long as it isn't stopping the other people from doing what they want. Reverting malzahar has virtually no impact on other players, anymore than the rework itself had. Except in the opposite direction.
