Well theoretically on first boss in ToT you could solo it IF you kill him before he grabs you and throws you (not gonna happen in toodays gear) OR get a way to summon a guardian (trinket like - Ghost Iron Dragonling or smth like that? ideally one you can summon when you need to not from a proc - wtb hunter pet/warlock demon) that will get aggro during the throw (AND survive long enough to you to get aggro back [you CAN bubble the stun btw - done it on progress as prot]). So good luck.
