This is a quick one but also simple: What if Vigilance Wing, along with healing you when an Ally dies, could also heal your Allies if you died?
It would be fun to see in PvP, like in a full team engagement; either the wielder is the last man standing from his team getting picked off while picking off the remaining enemies, or their team gains a chance to stay in the engagement a little longer from the moment of regen if they died first.
Nothing too crazy, but it would be a fun supportive element when doing strikes if it was added.
