Best zone(s) level 35-40

[TheBlob]

Hello,

I am currently a level 36 magician looking to level up. I know that Mistmoore Castle is a great spot, but you absolutely need a group to fight there. I am currently in Frontier Mountains, soloing blues at the entrance, but the grouping options seem rather limiter around here.

The amount of time and concentration that I can put into a single gaming session isn't always the same, so I would like to have the ability to group and solo.

My question is:

Is there a good zone which allows soloing for a magician of my level, as well as having some group action in the same zone, or in a zone which is pretty close?

Thank you!
