Wow people is overreacting to this, don't want to burst anyone's bubble, but soloing will not be easy, a soloer can't take down a primal ex, or certain HMs, CTs are out of question these have mechanics designed for various players, and even as lvl60 with ilvl170 some of the 2.4 and 2.5 dungeons will be hard to solo, and of course coil will be impossible at least without the echo, and even with it i don't think a soloer will be able to clear t4.

That said, i have done AK in duo, and AV carrying 2 players (almost duo because of deaths lol) many times, so most of the dungeons will be soloable.

Buuut... HYPE! i will love this feature.
