Saw a WHM with lvl 6 Arcanist, 50 Conjurer. Is this possible?

I dont understand why.
Me and a friend saw and confirmed we saw this white mage, with most class 50, except arcanist at 6, and rogue at lvl 3.

Please enlighten me.

I'm just assuming here but that player you saw was probably a version 1.0 player who had unlocked WHM in version 1.0, where the class requirements for WHM were actually different (in 1.0, WHM required GLA as it's sub class and not ACN, because ACN was dummied out of the game and unavailable.).

So, as 1.0 players started ARR with all their class levels and Jobs intact, this WHM would have ended up in the unique position of being able to equip WHM from the start without having unlocked ACN. It's just one of those little oddities carrying things across from the old version of the game has done. :)

Are you sure it wasn't archer? When I first started playing, I kept getting the abbreviations for the two classes mixed up for the longest time.

wow, thank you for your response, this might actually be the answer.
