Not sure how Personas work, doesn't it not share inventory between different personae? Can you actually share no-drop gear between classes?
Later expansions they make a ton of gear class-specific, so even if you can share gear between Personas, you won't be able to use the same visible slots from one class to another. A lot of non-visible slots are still All/All at least.
"Nobody wants to play a Paladin" is why I'm considering dual-classing SK/Paladin this time around. Can share most of their gear, and would be an interesting dichotomy, certainly something different. Can switch depending on what a raid needs. Also a way for me to finally try Paladin without giving up SK or wasting much time/work (given that anything gained by one can benefit the other, outside of AAs once they're a thing).
