I know there's never really been a guide for leveling in this game, but was wondering if anyone has some tips for leveling a jugg? Is DPS jugg still viable? I haven't played in ages. I usually just followed a class guide and used the suggested rotation/priority best I could. Any help would be appreciated.

If you're just talking about the solo PVE stuff, then levelling is simple enough. You'll be nigh unbeatable as an Immortal Jugg, but stuff will die way faster as a DPS one (I switched to Vengeance during my levelling just recently, so for me it was very viable).

 

The only real tip I can offer is to put your companion on heals if you want the easiest time. As long as you don't let them draw aggro, you won't die.
