People want change on difficulty due cant handle challenge and beyond, right?

Simple solution: put same loot from challenging or heroic to normal and hard and let difficulty as current state.

Others game like remmant from the ashes do that and this make people play in whatever difficulty want without need more challenge to get loot.

I have one week and already can walk solo on challenge and some friends already can solo heroic... people dont want farm builds and just want loot without work for this...so just give loot to everyone and keep players wanting challenge have a challenge.
