There are 2 mods here - one replaces dragons, the other replaces bone golems.
For the current replacement of dwarves, you can use the one from Tier 4, and Tier 7 is for the future, or play with it using the vanilla dwarves.
Tier 7 disappointed me; I got used to the fact that it would slide in place while walking, but I play with accelerated animation - usually this is not noticeable, but now it doesn't even match the sound of its steps.
I hope I get used to it, otherwise I'll use the smaller one.
Good ones =)
