I came across a pretty cool resource today, three Maya plugins available to freely download!
interpBlendshape - a way to create non-linear blendshapes for delicious non-vanilla blendshape deformation (face rigs!)
rigidWrap - a unique solution to bind rigid pieces (scales, armour etc) to an organic mesh but keeping their rigidity. Looks very handy!
meshController - a way to use deforming meshes as a means to control the mesh itself for intuitive selection & animation (again, particular useful for facial anim)
All credit to Zhenggang Deng, and pretty incredible that we're able to grab all of these for free from his site here: https://www.cgdzg.com/download_file/
