To me, it really matters on how the person plays the character and how their back story is set-up. I have two young characters that I play, one a monk and the other a Paladin, both are in their early to mid twenties and both are still very new at their professions (despite the monk being level 50).
Alexander on the other hand is in his mid to late 50's approaching 60. He has spent his entire life studying magic and the aether so his mastery of black magic (thaumatergy), has branched into other areas of study, namely conjuring and more recently the aetherial manipulation that arcanists use. These came fluidly, in my opinion, as he branched out, studied and gained more knowledge about magic, the aether and its uses thus why I consider him an archmage. Again, this is a lifetime of study and research he has put into these things. Now Alexander is in no way a physical fighter, he has no real martial skills to speak of, so I consider that the counter-balance.
