Farming for a haste item and some nicer weaps then soloing will probably be faster than soloing as is.

Instead of spending forever lfg though, just find a shaman and ask to duo. Necro might work as well, if they aren’t charm killing. Either duo partner would be great.

duos are fun

shamans for the win!

if not, druids are neat too

So you need a haste item and better weapons. For soloing you really want a nice 2hander (Staff of Battle comes to mind) and not fast proccing weapons. If you like dual wielding a Wurmy is surprisingly good. If you're flat broke, I can lend you a Swirlspine Belt, but I go out of town soon so get at me.

I solo'd a bunch on my warriors. I did random trash around CoM on Blue and on Green I did guards in Steamfont and Mistress Anna/4th floor guards in HHK as I was evil. Since you're good though, there's a solo Ogre Bouncer in the Feerrott that should be ideal for you once you get some gear.

Something that no one mentioned is Yetis in dreadlands. This is a great spot, not sure if your gear is up for it though.

Update: I gave up and just ended up tanking City of Mist Arena to 48 then Hole entrance after. Warrior is now 50. I won a haste belt from Sky and I invested in a Staff of Battle to solo with and WESS+Kunzar Ku'juch dual wield when tanking.

In my high 40s I could do Iceclad and Eastern Wastes giants. It was a pain in the ass but with enough bandages I could at least get a bubble or two while sitting LFG. The tools I name it earlier make it possible though not optimal. If I had Fungi and Velious weapons I'm pretty sure I could do it consistently.

At 50 I couldn't think of any place I could solo at so I just resigned to doing the Hole all the way to 60.

So yeah, here's the final path I took:
1-5: Starting zone
6-12: Nearby dungeon
13-16: Unrest yard
17-20: Gorge of Xorbb muddites
21-24: EK crag spiders
25-28: South Karana wilderness
29-36: Splitpaw (amazing xp, safe and easy kills-- probably the only fun part to solo)
37-45: Cazic Thule AoF pyramid courtyard (invis ring there then arrow pick blue cons)
46-48: Iceclad Ocean wilderness around the druid ring
48+: Gave up and did the Hole. I assume you can do city guards or Permafrost if you're better geared than I was

Grats, and Respect, for putting in the effort to level a war without twinking

This.

City of Mist is pretty fun. Sometimes you can group there. If not, just pick mobs off. Pull to ent if you get more than 1. Kill 1 and then zone, wait, then kill other one to break up camp. COM from 45-49ish
