Which of these champions do you think is most worth to 6 star first:

Gorgorab, Jareg or Zelotah?

My highest priorities right now is to farm Minotaur Level 15, Clan Boss and some Dungons

Arena is mid-prio for the moment.

Let me know your opinions.

Jareg is ranked higher by most content creators.  I personally don't have him.  Gorgorab might be better if the long term priority is in arena.

I use gorg and zelotah everywhere currently. Both are 60. Dont have jareg. Who do you already have at 60? 

Hi,

I'd say Jareg, he's an excellent support. I use him in my ultra cb team and I used him in the arena and in dungeons too, for a long time.

He also needs books, of course.

I use gorg and zelotah everywhere currently. Both are 60. Dont have jareg. Who do you already have at 60? 

I have Athel and Warmaiden at 60. I think its between Jareg and Gorg to be my 3th 6 star.

I agree with Valdy's

Once, you have a Brutal Campaign Farmer.

You should focus on Clan Boss

Jareg - Attack down is very useful in Clan Boss

I would also say Jareg, but he definitely wants to max his A1, so you have an Atk Down at a reasonable percentage chance.
