It’s not as easy as just running away. As I mentioned earlier, I tried getting to 70, and just running, and it took roughly 4 minutes for me before I finally got overwhelmed. The shield pylon lasts for 1 minute.
I was using a GoD build. It doesn’t have a movement skill that avoids combat. So, if I use strafe to escape, I end up lowering the bar, which only extends the time limit.
Plus, as you end up going in tiers, the monsters get faster.
And I was not using a DPS build. I was using my typical HC build, which was designed for survivability. But I quickly rank way past my tier that I could survive in HC, meaning more monsters and faster monsters. (They move far faster than what you’d see in a greater rift).
Blizzard stated, to test what you’d normally focus on. And that’s a problem with many streamers, and just the PTR in general. You get gear way beyond what you’d normally get in a season at that point in the season. With many streamers, that’s where you see “I did such and such with no paragon”, yet they’re running fully augmented ancient gear, giving sometimes 2-3x as much dps & defense as you’d have at that point in the season. I try to do my attempts with as realistic stats as I’d have in the season.
So no, I’m not going to have a build at that point in time which can survive multiple GR150 hits. And within a minute, I escalated to the point where they could one shot proc me. So, in order to survive, I need to use strafe, which then escalates the rift roughly 20 levels higher than I could possibly clear in a Greater Rift. So being one shot is still being one shot. So now, I have 3 minutes of being in one shot territory, to make sure I can survive long enough to pop on a shield pylon to let me survive the last minute.
As I mentioned previously, it’s not the fact that I don’t want to run away. It’s that the Echoing Nightmare scales up far too quickly, way beyond what I’d be capable of playing with my build.
EDIT
One last thing. Greater Rifts also scale health far faster than they scale enemy damage. This could also explain how people are able to get overpowered at higher greater rift levels. That is, if you can make it to 140+, you should be fine and hit the overpowered state. But if you’re at a point where you can only make it to 110, such as what I was at, you’re at far more risk at dying.
