vogoth maus mage and vrask all are excellent. I like jarl as well

And Turvold of course. Apo is also worth 60. 

Yes, Apo good choice. I think Dragon20 is your next goal and think Apo will be on that team.

I would make Apo and Frozen Banshee lvl 60 next. They will probably both be in your CB and Dragon team, Apo probably in all other dungeon teams as well.

Another vote for apothecary or frozen banshee.  They will continually be useful for your late game stuff
