Old crossfire- Fire an arrow. Bleed your target if you hit them from behind or from the side.
Crossfire should resemble more like GW1 crossfire.
New crossfire- Fire an arrow. Bleed your target if any of your allies is near your target.
This synergizes with the pet really well. It will also make bear pets more useful since it requires a living pet to keep pressure on the enemy. Bear pets basically says, Free bleeding attacks.
Also, it doesn’t just stop at pets. It is allies, so if you are using crossfire on a target next to your party members, the enemy will get bleeds as well.
