Guild Wars 2

If Symbol of Swiftness or Temporal Curtain is passed by someone with Swiftness on them, and the remaining duration is shorter than the duration that SoS/TC will apply, it should overwrite the boon and set it to the long duration.
Currently, if Swiftness is on someone who crosses one of those, they will only gain 1s of Swiftness from SoS and TC will do nothing, even if they only have 1 second of swiftness remaining.
I know that they don’t apply their full duration every pulse/crossing due to the ease of stacking Swiftness duration if it did so, but as it stands if you don’t time it right you gain little to no benefit even if you barely have any Swiftness left.

Examples: Player has 2s Swiftness, crosses SoS. Swiftness duration is set to 8s. If they stand on it, it will continue resetting to 8s (or adding 1s). As it stands now, gains 1s.
Player has 9s Swiftness, crosses SoS, only gains 1s swiftness.
Player has 13s Swiftness, crosses TC. No effect.
Player has 1s Swiftness, crosses TC, Swiftness set to 12s. As it stands now, no effect.
All of these are obviously modified by Boon Duration.

Swiftness from TC is not stacking with other swiftness because they “fix” bug what makes possible unlimited stacking swiftness from one TC. But now it works in the worst possible way and it needs to be changed. On my mesmer i need to wait to my swiftness is gone to put another TC, and when we zerg run on wvw it ofen happen that somebody is putting SoS, i step in to SoS gain a one or two sec of swiftness and then no swiftness from TC ;/ Then after 2 sec I don’t have any swiftness. I think swiftness from TC should be stacking but only once per player. Reseting duration to maximum after passing TC without stacking it with other swiftness is also an option but just secondary solution if there is no other way to fix it. Anyway it’s a big issue and need to be fix ASAP.
