The biggest lie ever told is a campaign task, Glory Hound: Earn Glory from ANY battle (except training).
What it should say is: Earn Glory from ANY battle (except Training, Underspire, Explore, Guild Events, Daily Events, Chests, and anything else that isn’t PVP).
Or just shorten it to: Earn Glory from PVP battles. 
Underspire earns you Glory.
I agree that Delves (especially Daily Delves) NEED to count towards the Glory task, but at least they finally made Underspire count for it (all 49 free Torches + 1 free Lantern will get you 102 Glory by end of week).
Before that, this task really WAS just a functional duplicate of “win PVP battles”.
The biggest lie they ever told is we will listen to your feedback 
Nah, they are just very good at multitaxing!
They listen, ignore and forget simultaneously! 
In the world of retail, “earn glory from any battle except training” would be considered false advertisement
biggest lie ever told … we put players first
And I thought the Greatest Lie Ever Told was “Easy to Assemble”
The biggest lie of all is that everything’s pure random. 
The biggest lie is “We are looking into the dragon duplicates prevention plan”… Wait for it in the next update… Two years after, several updates and nothing
not only that but additional new dragons to chase (Cosmic Dragons)
I’ve stopped buying stuff because of this issue and the sentinels. Constantly ignoring player feedback so keeping wallet closed
