No, not the same. Your right, but u can have two grenades with sunsinger skill. I know you speak of armor and not the abilities. I for one don't want or need any more exotic armor for my warlock. I have two chest pieces. One works for my void walker and the other works for sunsinger. Since we can only use one exotic armor item, its pointless to have more. Plus if I had an leg armor and a chest armor, it would be a huge hassle to switch abilities since you would have to carry a legendary equivalent to the exotic to replace it with. My hunter has two exotic helmets, warlock now two exotic chest pieces and my new titan has nothing.. lol.. You want speak of power armor, abilities, etc; it goes titan/warlock, hunter :/
