At level 50, you will be able to equip 5 cross-class abilities from other calsses you have leveled onto your paladin to make it unique. For instance, you could equip cure, protect, and stoneskin from a conjurer, or foresight, bloodbath, and mercy stroke from a marauder. I'm not exactly sure all of the different cross-class abilities that will be available, but there should be plenty of options for those 5 slots to make you feel unique, and to also swap in and out based on circumstance.
Ah. That was something I've missed while researching. So that also gives me an incentive to level up other classes. That sounds interesting.
Will more classes be added in the updates to come? Or just jobs?
Thanks for the reply.
