Possible bug I’ve noticed occur in the Heart of the Mists and in WvW. Could be game-wide, but I don’t PVE much, so I don’t know if it occurs there as well.
When I use Illusionary Leap (both parts of the sequence skill) through Temporal Curtain to create to create Retaliation, I often don’t get Retaliation even though the combo field “indicator” (heart visual with the word “Retaliation” inside it) usually appears.
Even while standing on top of the Curtain (exactly in the center of it) during both parts of Illusionary Leap, sometimes it will show the Retaliation heart visual and not actually give me Retaliation or not even show the visual and also not give Retaliation.
