For the hunter, I would give it a support class of some sort, so they can help more in raids, as the Titans already have ward of dawn and warlocks can resurrect themselves. This may sound weird, but what about a super that could revive teamates from a distance? It could be a bow (as people have already said) with something on the arrowhead that revives downed players, but can also be used to hurt enemies (for crucible) but it would only have one or two arrows. Something like that. I just think they need a support class of some sort.
