Because its not a bug? Glorious Foreshadowing is applied only by directly using WoH, its not a byproduct of it, so WoH stacks obtained from rousing words are not subject to the same benefits as if you would have just used the WoH skill, it leaves the HoT not the buff.
I'll quote the trait tree and skills directly: Rousing Words: Allies affected for at least 5 seconds WILL GAIN A TIER OF WRIT OF HELATH <-- this teirs up writ of heal... same buff...teiring up and down...
Glorious Foreshadowing: Incoming Healing is increase by 5% for EACH WRIT of HEALTH Tier on a target. <-- thus Glorious foreshadowing should be going up and down with Writ of Health regardless of which skill cast the Writ of Health.
However. this does not work... if you cast Writ of Health, you have the T1 +5% buff and T1 Writ of Health. If you then cast Rousing words, Writ of Health properly tiers up to T2, but Glorious Foreshadowing misses it.. You now have T2 writ, and T1 Glorious. Casting Writ of Health again increase writ to T3, but Glorious only increase to T2.... further... if you work all the player up to T3 and then use Rousing to keep it refreshed...the Glorious Forshadowing can time out while you still have a T3 Writ
Suggested Quick Fix: instead of Glorious foreshadowing being an independant buff, just delete it and when you acheive "Glorious Foreshadowing" in the trait tree update Writ of Health directly to have the added Glorious Foreshadowing +5% per teir...simpler and won't get out of sequence...
