With the release of 3 4 person dungeons in each patch has there ever been talk of having gradually increasing difficulty curves with each one.

Rather than having all 3 dungeons at i55 why not have one i60, i65 and i70 as more of a sense of progression because with the current build of dungeons players will more than likely only focus on the one which provides the quickest means of obtaining mytho/soldier aka Brayflox HM. Loot becomes secondary in these dungeons because at the rate in which mytho/soldier can be obtained aka i90/i100 gear outweighs the i70 gear which comes from these chest.
