How do I kill Zhaitan without others?
http://www.gw2lfg.com/ would be faster than map chat but most people are just not interested in Arah story mode unless they happen to need it as well. It’s not particularly rewarding(same can be said for pretty much all dungeon story modes). The only thing that might make it worth it is the PS rewards.
Even tough story modes are unrewarding and not much played, I recently played through them all. If you can get 1 other ppl (friend, guildie, total random) and make post to gw2lfg (saying you need 3 more, and keep it refreshed) you should have full group in max 30mins. Atleast that was how it went to me when I went all storymodes with my friend. There is allways few guys who need to unlock exp mode
Guilds are the best way to find people to play with. My guild runs stuff like that relatively regularly.
Getting into a good guild makes a huge difference for things like this. Even if people don’t need it themselves they’ll often come along to help out a guild member.

Killing him without others is (or atleast was) possibly. It will take very long, it’s incredibly boring and is a total waste of time. Better to find those 4 other players.
