Guild Wars 2

Powerful Synergy can grant the warrior a 10-second fire shield

King of Fires easily overwrites it with a 5-second fire shield after a critical hit, and/or removes the shield after using any Rage/Primal Burst/torch skill

to reproduce:
equip traits Powerful Synergy (tactics), King of Fires (berserker)
wear a mainhand sword, a torch, and a Rampager amulet
use Flames of War (torch 5), followed by Savage Leap (sword 2), and then any Rage/Primal Burst/torch ability, or connect with a critical hit

Savage Leap triggers a 10-second fire shield through Flames of War’s fire field, and then any Rage/Primal Burst/torch skill will remove that shield. alternatively, any critical hit will reduce the 10-second fire shield to 5 seconds

The aura goes away cause you are detonating it to burn the target.

Auras dont stack so longer duration auras will get overwritten by shorter duration ones.

this much is obvious, but wouldn’t you think these traits should synergize rather than conflict?

Eh, theres alot of weird traits like that, like the two from the dragonhunter line that wants you to both use and not use F1

is there anyone who wants to add without just trying to invalidate a concern?

To answer your question: Yes they should synergize. Obviously there’s a quality of life conflict, albiet poor mechanics present.

Perhaps a simple solution would be that an aura explodes whenever a new aura tries to take its place. Submit a bug report, and even add the suggestion.
