Well, they need to come up with a reasonable upgrade and create better and more original abilities for all creatures – there should be a couple of completely new abilities, otherwise, how can we talk about the originality of the faction?
Lava Elemental – quite acceptable and fits the theme, I already explained why there are no archers, and the abilities – IN THE GAME (I don’t really want to change what I didn’t come up with myself...), Fire Spit and some other stuff – completely new, what else?;) ;) ;)
P.S.: Please, post all your questions at once, because you write so rarely
