I imagine your problem is your "brand new toon". I understand you have used the lvl 110 boost. As far as I know these toons have not one single AA-point. All spells are on lowest lvl, no epic 1 and/or epic 2 spells, no ascension ect. All what you have is the gear from panda and tishan. Of course this is a kind of worst case situation, but I believe even under theses circumstances CD solo is possible. Ok, you are right concerning the time of a fight, but with every named you kill you drop a legendary chest. With sig-line you get around 10 pieces of good at the end very good gear.By doing quests you can develope your ascension. In addition you fill your AA-trees quickly. The fights will become faster with every finished quest. Within the questline I reached already more than 50.000 pot. With doing missions, infusion of the gear and so on, you can reach 60.000.Till today I was not in one single heroic dungeon. Nevertheless I have a proper equipment. Sorry, but you want it too easy. You want to jump from zero to endgame. That is always difficult and it has to be difficult. Of course a lvl 110 booster is helpful, but before you try endgame you should go back to older content and improve your stats and spells to a certain minimum.
