If you brought a healer with you then you didn't solo it .
If you want to say you did all the killing and finnished the quest well then that would be correct.
But once again we dont know what spells the healer used to help such as any croud controll plus
you were being healed but another.HEALED BY ANOTHER = HELP doesn't eqaul solo.
I am not taking away from what you have done but I will correct you in saying you were not alone.
