Wow, that's interesting that people play that number in your area

I had the same reaction at first! But it's all about matching what people play near you!
I think, with the modelling I've seen you do, you could go more for a dragon theme through your conversions, rather than just unit choices.
For example, if you want a lion chariot, you can have flesh hounds pulling it instead of lions (they look very dragon-like to me). Similar for the swordmasters... some sort of dragon on their helmets?
A dragon and dragon princes, and especially a dragon mage, are not the strongest of HE units in 8th from what I can tell (dragon mages never were) but could be viable if your whole force is fast and hard-hitting,
imho. Jin can probably say a bit more as he's been using dragon princes! Although they haven't beat face too much from what I've seen.
Anyway, that's my feedback... that you could pull this off from a modelling perspective more than a unit one, if you like. Obviously, a dragon needs to be included, but after that I'd say everything's fair game!
