I didn't want to instance because the content of each vertex buffer was different. It was something simpler than the draw calls. I'm unsure how to refer to individual (indexed) vertex data in the index buffer... If I need to of course... and also confuzzled about how to wrap the data in a class for transforms. I thought about the cpu option, but my storage structures were in the heap and transforms would be called every single frame -or updated when changed... and it defeats the use of the GPU. :P
