Being a level 17 gladiator, my goal is to become a Paladin. When do you know it's time to start training the conjurer class? I know I have to get to level 15 for a conjurer and level 30 for my gladiator. If I get my gladiator to 30, and then I start training as a conjurer for 15 levels, does my gladiator stay at level 30? Sorry. This is really confusing coming from WOW and Neverwinter. And if I want to level the Lancer for some of their skills, when would I start to level a lancer?

Is there a limit on how many classes I can train? And if I do, will my Paladin ever get to the max level?

Thank you for any help!
