I main a Titan. I agree that the Hunter ability could use a buff for sure. Personally, I think the dodge is a bit weak for their whole class ability. I'd give it to them as an ability they can all use, but put it on an internal cooldown (likely shown as a debuff like Icarus Dodge). Class power would be something like "Agility" that is "Hold crouch to gain XYZ." If you want them to be helpful to the team, just say... Assassin's Agility - Animation would throw a smoke bomb at their feet and turn them and nearby allies invisible for a short time. Possibly also paired up with bonus melee damage, but that might be a bit much. Ranger's Agility - Animation would be them pointing forward to direct fire or something. Grants them and nearby allies bonus precision damage for a short time. During this time, their dodge can be used without incurring the debuff, allowing them to use it at will. Something like that. Supports them and keeps them as the more lone wolf class, but also helps them act as scout and infiltration team experts. Kinda just talking off the top of my head, though, so I dunno.
