Deep Strike trait issue
This has actually been around for a while. It is not that annoying unless you happen to be swapping it with another trait all the time.
The simplest way to ensure it is working is to switch signets to something and disable the trait. Re-enable the trait then select all your signets again. The bug is probably caused by the change to make the amount of +precision scale with level.
I’ve read on the notes for the april 15th update this:
“Deep Strike: Fixed a bug that caused bonus precision to be calculated incorrectly. "
Unfortunately, in my experience now the bug is even worse than before. Now the percentage on the hero panel variates wildly and without any sense, especially in combat. Furthermore, the passive increment of precision given by the trait is still inconsistent. Please note that I’ve observed this behaviour repeatedly in lvl 80-only places like fractals and cities, so I’m pretty sure that the issue is not related (at least not directly) to level scaling.
