When I join a match in sPvP, though my signets are equipped, I get no passive benefit from them until I either die, or activate them, then wait for them to recharge fully. This gives me a huge disadvantage because as a Ranger, I am slower in the beginning of a match due to having to activate my signets so that they’ll work. It also does not matter what class it is – it happens on Thief, Ranger, Warrior – any classes with signets.
Here is a picture demonstrating the bug where you see the signets are equipped but there is no passive benefit from them (which you usually see to the right of your health bar).
