Hi, 

I need some advice and opinion about how to set up my teams on different features in the game. 

1. So here is my mains account champions

My arena team for now is Royal Huntsman, Crimson Helm, Skullcrusher, and Doompriest, and I think it's ok (IV gold tier).

But I have problem with my Dungeon teams and especially Clan Boss. What do you suggest? I hardly make 13 lvl of dragon and golem, 11 lvl of fire knight. And I just take 3mln dmg on CB hard.

2. I also have the second account with champions below

And there is similar problem, My arena team is quaite good now: Sinesha, Nethril, Jinglehunter as leader, and Atur.

But what champions should I use and develop for CB, and other dungeons?

And which of there three champions should I go 60lvl first? Sinesha (full books), Nethril (A3 2 books), Septimus.

Thanks for your time and answers :)
