I'm really not sure Wolf's Heart is a smart addition... Even if they lower the HP of the crate, it's yet another PVE element in PVP content, on top of double adren boxes and double offensive crates to take care of. This is leaving too much time for healers to breathe and top off their party. And give WH to a good dps they are going to wreak the enemy PT (does it stack with off buff? That'd be even worse), or give it to one of the best healers and you're gonna need really good coordination to take them down.
