Disagree would be way to OP pve. I like the way sunsinger is set. A possible third class would be an arc class. The arc class could give each of the fire team members +arc damage. So if they have solar damage already it'll give solar and arc. an arc charge with a blink that would teleport past opponent putting some arc damage or stun an opponent. jumps would be normal warlock jump maybe an arc teleport? grenades arc paralysis, just stops an opponent area from moving (opponents can still shoot) in a certain area. arc buff throw a grenade at your teammates and they get shields titan solar body the body is covered in flames reducing damage and opponent who touch them puts ignite. or solar flared body where the titan explodes into a giant solar flare that can move. magma grenade area control regular jump etc dunno hunter not sure haven't played this class yet...
