War solo 24+

[Troxx]

If you're twinked should be able to solo with minimal pausing for bind wounding (assuming you've been working on it). It's honestly probably faster than duoing with a healer as you'll be putting up most of the killing power and bind wound (contrary to popular belief) is fairly potent at low levels.

Finding the ideal spot is the only challenge. Starting a fight at 50% doesn't give you much wiggle room if it hits the fan.

For that reason I'd personally stay out of dungeons. Yes the xp mod is nice but you'll probably end up on top killing in safe areas like the karanas where single pulls are nearly guaranteed.

Gnolls in karana to 20ish followed by south karana to 28-30 would be my advice. Stick to open zone old world areas of kicking it solo. Finding a single partner of any class will open up a lot of other areas. If duoing with a melee, just make sure they're comparably twinked or you might find them just slowing you down.
