Not to mention if they did change this to a 2-second refresh window, then that’s completely contradictory to the Ignite tooltip.
I’m seeing more and more mages saying that it’s down to two seconds. However, I was monitoring Ignite duration with Weak Auras very closely last night. Everything I saw looked like it was up for the full 4 seconds and I was seeing stacks refreshed after the 2-second mark.
The confusion with this is only getting worse and someone from Blizzard needs to give a full rundown of what this change was.
