No one forces you to use WoR. If you want challenge, you can use something else. For casual players WoR is fine and for hardcore players it is too OP. There must be a middle ground so everyone can be happy. Leave WoR alone so the casual community is happy and add something like the nightfall modifiers that you can chosse to make it challenging fof the hardcore players. I bet that most people here don't want to go through another nerf wave like at the begining of this season.
