hmm, last time i played svarts was with 24d but back then their archmages DID have a unique graphic, not the standard blue robed guy. not one i m very fond of (their adepts/illusionists look way better) but it was unique and no sex change involved.
however, as already posted somewhere before, i wish someone could do a adept/mage/archmage graphics revamp.
doviello have cool looking adepts/mages but their archmage is the placeholder (blue robed guy) that doesnt fit doviello at all.
balseraph have a cool looking adept but their mage/archmage is the placeholder that doesnt fit doviello at all.
in both cases (and theres probably more civs who have this problem) it d be much better if the adept model was used for archmages too, HOWEVER with a slight differentation so you can tell apart an adept from an archmage. see the mazatl for example - the only difference between their adepts and (archmages) is how big their staff is. (bigger IS better afterall

) not the ideal solution but certainly better than having a blue robed human as their top caster ...
would also be nice for svarts as their adepts/mages look much better than their archmage.
wish i could do it myself but i have zero moddelling experience....

completely different topic:
the immortal change planned for patch I rocks HOWEVER i d suggest taking it one step further: how about archmages also being able to become immortals ?
in tradeoff i d suggest "nerfing" lichdom. basically the new lichdom would no longer create a new unit but instead merely make the old archmage
have changed stats , changed art etc. but it d still be an archmage and thus count towards the limit of 4.
Death is already one of the most powerfull spell spheres there is in FFH and lichdom makes it pretty much mandatory for anyone interested in a magic-heavy game.
If you could get your extra 4 archmages from immortals instead ( mind you thats alot of extra research required) that d be more fair for civs that want to play magic heavy but without focusing on death.
and for those who love death its means they could have 8 liches, 4 normal ones and 4 immortal ones.
every side wins in this one i think, especially the "flavour" side.
EDIT: just incase , what i mean with nerfing lichdom is changing it into a promotion
this promotion changes race to undead, changes graphic to lich-model, gives the caster + 2 unholy STR (or whatever lichs have above archmages right now, i dont remember for sure) but the caster remains an archmage still and thus counts to the national limit of 4.
archmages would however now be able to upgrade to immortals and since they obviously keep their promotions you could then have also immortal-liches (str 9 + 2 unholy ) if you desire so.
so no matter whether you have Death III, if divine essense and strenght of will are researched, you would now be able to have 8 "tier3 casters".
