I support Tiberius and Tienity!An extra unit is an extra unit!All dwarven realms should have both differences and balance! :-) And all Draco says is basically that he loves "his" "perfect" Erebot and want it to be the strongest and more uniqe than other's!While each fraction has its strengths and weaknesses an extra unit is no fair for the other! :-)
I support Tienety's idea too, since we are not talking about Dwarven 'Subfactions', but Dwarven 'Factions', with relevant differences that define them, given also the different physical environments in which these realms were established; still remaining, obviously, factions of a common Dwarven Culture.
I personally like the ballistas and the Ram Riders concepts, also because they would symbolise very well what the Iron Hills are at that particular moment, an impressive warfare factory with a lot of creativity, militarily speaking
I'm generally always for innovative (not too much strange or grotesque) concepts that give us a richer and more diverse representation of the different elements of the respective factions.
This is incredible, well Im agree with Iron Ballistas, camon even with the ridicoulous ram riders, but the earthshackers? camon this is pointless in comparison with a lot of balance bugs that the mod have now.
I find instead the Ram Riders one of the most characteristic concepts of BOTFA (apart from the other over the top things) and very interesting, that could explain wisely what means the Dwarves of the Iron Hills use in their realm/environment.
I personally think that this concept would fit very well in the Edain Mod, as for the other BOTFA elements that were rightly implemented in the game (Lord Dáin's concept and Thorin's royal armour).
