I think its a known bug, but i didnt see any threads about it and the searchbar doesnt function for me.
You have three utility skills: “utility 1”, “utility 2” and “utility 3”.
If you have “utility 1” on cooldown and swap for example “utility 3” with another utility, it gets the remaining cooldown of “utility 1”.
Once i was on warrior, had my banner on cooldown (around 100 seconds) and swapped the two other utilitys and i had all three utility on cooldown of 100 seconds.
Maybe you guys know exactly when this bug occure.
