Arah path 4.
The other Arah paths are still far more challenging than people are used to in the average other dungeon, though. In my experience, path 3 and 2 are quite doable, even with pugs that know the basics/have some experience. Two days ago I completed the mursaat path (3) with a pug (me being guardian) and only Alphard the mesmer boss gave us significant trouble.
AC is considered the easiest and fastest dungeon and I'd rate all paths of TA and HotW (and CM - although it can be annoying, it's not people's favourite) also as quite doable.
It´s just that doing dungeons requires quite another playstyle and mindset than levelling. Once you´re level 80 in exotics and are used to it, it´s usually not all that hard; there's really SO MUCH difference between playing AC as a lvl35 and as a downscaled lvl80; you really do a lot more damage and you can take far more damage as well. I also think that storylines are far too hard for the appropriate level players, some are even harder than some of the explorables.
If you know what to do (which can be quite tricky) most dungeons get a lot less challenging. And yes there's exceptions, some dungeons have one path that's particulary hard.
Just did the mursaat path today. Total nightmare.
I hope some of the other paths are more manageable than that. I'd hate to forsake Arah altogether.
Sorry but path 3 is generally considered the easiest.
