SotR uptime increasing with next application.

So...either I've missed the patch note or just been blind for some time. I've briefly looked on here for the answer or question but haven't found it.

Last night while working towards Ji'Kun for our heroic attempts I noticed on Magera that my Shield of the Righteous was at 14 seconds of duration left. While I noticed this in a Weak Aura I had setup I immediately looked at my default buff UI and saw the same. Has this always been this way or is this a recent change? Bescase as long as I can remember the next application always just pushed the timer back to the max amount and that was it.

Here is a WoL link Magera 25N

Yep it's been like that since release, with HA up and some lucky procs you can easily get a 20 sec buff

exactly, every SoTR adds 3 seconds to the existing buff and it has been like this since prepatch MoP.

although pay atention, it snapshots your mastery at the moment of the first SoTR and keeps the reduce level constant as long as it is up. so every mastery proc while SoTR is active goes to waste.

this is why "on use" mastery trinkets should be used before SoTR and HA.
