Guild Wars 2

Before today’s patch I remember symbol of swiftness has no max-limit , right? As long as you pass it before it disappear, you get the swiftness buff.
However, today, I followed a big zerg in WvW, I kept passing numerous symbol of swiftness but I got no swiftness at all……until I cast my own symbol.
Since when it got ninja nerfed?

It has always been buggy for a long time now. :/

It isn’t bugged, people just don’t understand the mechanics of it.

1) It is a pulsing aoe. It pulses about once per second, if you miss the pulse, you get nothing.
2) It adds 1s to your current swiftness buff (plus boon duration) if you already have it.
3) It doesn’t trigger as you enter or leave, only on the above mentioned set intervals.
4) It has an aoe limit of 5. So, when following a zerg, you may not get the swiftness buff at all. This is fairly common.
