I already posted a bug report, but I would also want to know if you noticed the same behavior. Blessing of Autumn from my time measures IS NOT reducing the CD by 30% as description states.
If it would 2 min CD would recover in 84 seconds - Vision of Perfection was a 25% reduction for Avenging Wrath and indeed - instead of 120 sec we had 90 sec which actually really was 25% reduction. Meanwhile it reduces 2 min CD to 1 min and 50 sec CD, and 45 sec CD to ~~ 34 (maybe 35) sec.
It would appear that Blessing of Autumn can reduce the CD by a maximum of it’s own duration x 30% which is around 10 sec cap. We can easily see this behavior on Divine Shield - if we use Divine Shield right after using Blessing of Autumn UI will tell us it’s around ~~ 4 min CD. But after blessing goes off it suddenly spikes to 5 min again.
“Blesses an ally causing their cooldowns to recover 30% faster for the duration of the buff.” - that description is more true than in-game one. Anyway this CD reduction is pretty underwhelming if that’s the way it should work.
