I've honestly never liked the idea of dragos as a seperate race- they just can't have enough variety in units that makes sense. I prefer the typical seperation of infantry, archers and cavalry, but that's just me. I also didn't like the idea of minotaurs because it makes no sense based off what I've learned of them. (mythology) You'd have to bascally re-create all the ideas behind them. The only viable, addable races that make sense are dwarves and (unmentioned, but I'll put it anyways) gnomes (
Gotta love em').
Dragons, minotaurs and even the other aquatic based race with the weird name, all work better as utility/special units in my opinion. I simply can't get my mind around how you'd make them playable- both dragons and minotaurs have very few possiblities when it comes to unique units, and the aquatic guys are just that-aquatic. Not every map in skirmish can have water, and as mentioned at some point, how would you attack their city in mmorts?
I know some people will disagree with the above thoughts, but I simply had to post it. Heck, if Reverie can come up with a good way to implement it, power to them. Just my 2 cents.
