Paineel

[fadetree]

You will not need to be in paineel for anything later in life.
(I hear that) the faction grind in warrens is LONG...as in thousands of kobolds.
I read that they drop around 11pp in weapons and change, I assume that's mainly for the weaps and shields.
I don't know the xp but its probably normal, neither bad nor good.
To get in without faction, all you need is a buddy who is willing operate the elevator for you.
Now I am out of info, but I would say that I would be leery of going in there solo as a 18 ranger with no key of your own. You have no CC yet besides root...you get harmony at 22, which would make it a lot safer, except it's probably inside so you can't use.
