Greater Rift Key Stone Rank

[Devile]

I don't see it as a exploit at all cause the game was designed that way, otherwise imagine the nightmare it will be for multiplayer GR. U can't party with someone unless u do a trial first or have that specific key everyone else has. They added this feature so u could use the next higher GR key and be able to play with others. I never liked the phrase "clever use of game mechanics" but in this case it actually is.
