I really would like to try a NG+ I dont like ALL the randomness that NG has I would like to make a fairly marathon safe run

PotatoBacon D3 has speed run achieves in game "Complete Act X in under an Hour" the way people that aren't affileated with Speedrun.com do it is they have lvl 70 characters geared to what ever and then set it to normal dificulty. They are use all the paragon points they want because damage doesnt matter and move speed is capped. They then proceed to play as fast as possible and the only aspect of the game that is random is the generation of the maps. I think that a NG+ would be seriously fun to do especially routing this NG+ 4 players. I think that having NG+ as a possible run would be a ton of fun.
