I would say it's complete nonsense (no offense). A clone of elementals – 1, divided into 4 elements – specifically the element of fire – how many units are there already in the original game and the expansion? – 2, phoenixes definitely shouldn't be buffed, or it will ruin the balance – 3, a young fire dragon – firstly, there already is one in the expansion, and a fully-fledged one for the dwarves at level 7; secondly, I can't imagine a dragon being that weak – 4, and then, there's no need to make purely fire-based units anymore – it will create a conflict with the demons, or they'll add three more races for each element – no, that's not a good idea – 5.)))
That's it, I'm out of ideas))))):D

Firstly, I HIGHLIGHTED – it CAN be edited, and I only took elementals (1), phoenixes (2), and fire dragons (3) as a last resort (I couldn't think of anything else). As for the demons... show me at least one demon that consists ENTIRELY of FIRE AND ASH?! (4) And besides, maybe they are allied races? As for the other elements, what can be done there?! Air – it is what it is, and you can't do anything about it; water... well, you can still come up with something for water, but as for earth... if you suggest "unity with the earth" (like some more elves), it won't be the same – because it should be ENTIRELY of FIRE AND ASH, and as for the "new elves" (see above)... make seven stone elves, and then we'll talk...(5). That's basically the answer to all your 5 points.:D
P.S.: If you suggest what to replace the neutrals and the fire dragon with, I will be very grateful.

And what's the problem? Who will be bothered by four more races?!

And besides, you (AlexGhost) won't be offended, will you...? :D :D :D

Everyone already knows my point of view – the more, the better!:D
And I want a lot, a lot, a lot, and even more)))):D

And what will be the problem if elementals (at least fire elementals) belong to a certain race? Personally, I'm not against it
