One very nice solo spot, that is unfortunatly very difficult to access... is the "pal epic" raid version of vxed. Problem is a pal thats working on new epic has to start it.. and you might even need a raid to start it.
Pulls are single if your careful, all red con, and worth over 2 blue each. They were a little tough, but I could solo them with a little downtime.
I later tried a normal vxed expedition solo, and the blue cons there stepped on my tail muchly.
I have a friend with a lvl 70 paly that i can use How would i use him to start this?
I'm not familiar with the paladin epic ... but go through paladin epic 1.5 up till the point is the only way unfortunatly... I'm not sure if it's trivial to restart the expedition later or not... but if it was you could just get them there and re-get the instance whenever you wanted.
