I think any modifications to the main six elements is a mistake. The first Toa team needs to be the Toa Mata if for no other reason than for name recognition. One of the only reasons G2 was able to do as well as it did was because of that name recognition, introducing us to a team of ramdom Toa we’ve never met, or even other canon Toa, is a recipe for disaster. I know that the Toa Mata have a gender diversity issue, but that can be solved through gender diversity amongst the matoran as well as other Toa that could be introduced later. In this topic:
I formulated a pitch based 90% on the ideas discussed on the podcast just reorganized into a coherent story. Part of it involves introducing a large number of new Toa in the second year which could be easily used to increase gender diversity amongst the Toa, and later on in the topic I explored how one could incorporate the less common elements into them.
