I finished at wave 30, and got the key of 21. It happened every time too for the 6 time I took this test.
Grimiku: I just ran a quick trial to see what happened and had a very similar result. So, I went ahead and dug around to see if it was a bug, or something we had changed on purpose, and what the general philosophy behind it was if we had.
It happens that this is an intentional change we made to prevent players from sometimes starting in a Greater Rift they can’t advance beyond. Each trial wave tends to be easier than the numerically equivalent rift difficulty, so it was possible for folks to place themselves in a Greater Rift they’re likely to fail. We didn’t like the way that felt, so we made some adjustments to help ensure it didn’t continue to work that way. Currently it’s set at a 3:2 ratio, so completing 15 waves in the trial will result in earning a Greater Rift Keystone 10.
That said, we’re not 100% sure about the current tuning of wave-to-difficulty ratio, so we’ll be keeping an eye on it. Thanks for the feedback and reports, everyone.
The logic of giving a GRK of the appropriate level is sound, but that 3:2 ratio seems destined to confuse everyone who doesn’t know. This will become the new “why does not the legendary plan I just found show on my Blacksmith?” perpetual question.
Perhaps the devs could adjust the composition and timing of the waves so they correspond to the equivalent Greater Rift level?
