I agree with others - it all depends on the execution and the IC reasoning for it.
Claire is going to have dabbled in all of the melee classes, though I've not picked which one she's going to have as her primary class, as I dislike how Gladiator plays now. Her reason is that she wants to be able to defend herself somewhat, regardless of situation; that doesn't mean she'll be even moderately good at many of them, and that definitely means she won't know advanced techniques for all of them.
Kyma is going to be primarily Arcanist and Scholar with a little bit of Conjurer (as that's what he originally was in 1.0) ICly, with some possible Summoner (I'm still debating how I want to handle Summoner, given you have to have killed each Primal to summon in lore). He's starting out generally bad at magic aside from summoning, and will get better with magic (healing first, then damage) over time. ACN/SCH/SMN are all from the same branch, so I don't fault anyone from using all three in RP, if it's done tastefully.
