I remember reading a while back that Bungie fixed the sunsinger scorch knockback ability, as it wasn't working in midair (correct me if I'm wrong). One thing I noticed is that now whenever I jump and scorch someone while I'm in the air it will knock them back, but I don't have the knock back ability equipped. I use the fire shield because I'm jealous of titans. Can anyone else confirm this? I've been getting some cheeeeesy melee kills in PVP by bouncing guys off the map. I'm not complaining though.
