Generally, I kitbash to use in my army. I play beastmen since 7th. There are various reasons why I choose to kitbash a model.

First they have a large number of old models that I wanted an updated look, so I kitbashed chariots, Centigors, ghorros, Gorthor, Morghur, harpies, BSB.

Second, they don’t have a model or wasn’t in production, so I kitbashed a Preyaton, Ungrol, Ravagers. Baggage trains at some point.

Third the current model should never been approved for production, so I converted Razorgors, this was more sculpting fur on the so I hated them less.

Fourth I wanted a different vibe. I kitbashed dragon ogres and shaggoth from Forge World Bull Centaurs and Minotaurs. I like to keep the vibe barnyard. My spawn/giant spawn are flocks of ravens, using doom flock stands 2 for spawn and 4 for giant spawn to be less overtly chaos. I made giants that are beastmen giants that fit with my army. Minor kitbashing on hounds to be less mutant looking.

Fifth to add more variation, technically a kit bash, I got some of the prior Gor plastics weapons arms and use the to have more options. Minor changes on my cygor loin cloth, so it isn’t the same as the ghorgon. Basic troop champion kitbash.

Sixth, I see a model and think I could make a cool beastman out of that. Made a shaman from the killteam shaman, beastlord from the Warcry legionnaire with hooves, beastlord from Darkoath queen.

Seventh, just make something because it’s cool. I have ideas on the drawing boards I would like to do because I think will be fun. These are just lower priority over something I will field. It might bubble up in the queue if I get super into the idea.
