I was wondering if warrior-mages were planned for the High Elf roster, or if it was an intentional design choice to leave mages and warriors separate.
Many AoF players have models for three warrior-mages that belong to High Elf lore and some of us even have armies themed around them
A dragon-riding mage with some combat ability
A Sword Master who is also a master of lore
A griffon-riding prince with some magic
I think the easiest way to include these would be to update the 'upgrade' entry A in the HE roster from Upgrade with High Prowess +30 points To Upgrade with one of High Prowess +30 points Wizard (1) +X points
This adds a warrior mage option, but keeps it distinct from combat specialists and high level wizards. List building has more choices, but no one is clearly best.
And it lets you add options for 3 heroes that many of us own models for by adding only a single line to the roster.
