Destinies difficulty depends on the characters, warlocks would be easy mode, titans would be medium, and hunters would be the hard-core mode. I noticed once I created a warlock how easy the game became. I don't have a titan but my brother does. Also hunters aren't that squishy, you can actually put there armor rating really high while keeping it's great agility. Also agility does matter whoever thinks it isn't useful is kinda dumb, and using golden gun does save your team some heavy ammo, especially when it comes to taking out minotaurs/protarians. Me and 3 of my other hunter friends 4 manned the raid a while so yeah I find hunters to be useful, but I do think it's important to have, at least, 1 warlock and titan. Dream team is two of each.
