Actually for Bullcentaurs in Kings of War there are two different units of Bullcentaur like creatures, one in normal Cav sized (Abyssal Hybrids), one is monstrous Cav sized (Abyssal Grotesque) so you can use either or both. Also with the “counts as” rule being tournament legal you don’t have to worry so much about it really.
The TH weapon guys work pretty well in Kings of War, but in my experiences using the two-handed option actually inst often a good choice- however you can for example just add the �?oPotion of Crushing�?� or “Potion of Sharpness” to a normal unit of guys and represent their increased killyness (which in the case of Strength is the same benefit as having TH weapons) with said TH-Axes. These kinds of creative modeling options are actually once again not only tournament legal in Kings of War, but they are encouraged, so long as your clear with your opponent what they are and that it makes decent sense.
My only trouble is that in KOW their inst really a good unit to represent the Kadim Titan on the Abyssal Dwarves list, you have the Greater Obsidian Golem, which is a really great unit don’t get me wrong I love mine to pieces, but it dosent have any shootyness or quite the killing capacity I feel like the Kadim should.
