Immediately with the 1.04 patch, I started to notice the Monk popping back to its initial starting point while using Tempest Rush to get away from a mob. I first noticed this with Elite Packs and thought it might be due to the Vortex affix.
After that, when I saw this behavior, I would look at the affix's to see if the Elite Packs had Vortex which often times they did not.
I started watching my Ping delays to see if Lag Spike was causing the issue. My latency meter would update regularly between 75-86 ms, and I have still seen the issue.
I believe I have seen this issue with large mobs that do not include Elites, but I am not certain.
When I escape the mob with Tempest Rush, I can run for up to 2 or 3 seconds then pop back to my point of origin. The level up Spirit I used up to that point is spent, and more often than not it leads to death due to no other resources to escape.
I have seen this with a wide variety of configurations as I have had to re-invent my skill set to proceed through Inferno difficulty. I have seen this in Acts I, II and III.
These skills have always been part of the configuration along with Tempest Rush:
Breath of Heaven: Blazing Wrath
Serenity: Peaceful Repose
Sieze the Initiative
One with Everything
Beyond that, I have seen the issue while every one of the Mantras have been part of my build. I have also seen it with every one of the Spirit generating attacks as part of the build, whether the attack had a teleport effect or not.
