The simple explanation: These "playstyles" are nothing more than a tool for milking even more money from players! Nothing more, nothing less. An incremental and pointless update to the actual game mechanic (where they maybe could make it a bit better God Forbid!) but one more trivial bs for their customers to pay attention to and spend more cash!

Pretty rudimental money milking strategy with minimal effort expecting maximal profit. Karma is a beautiful force and they will eventualy deal with it in most beautiful and powerful way possible!
