I have know idea where people are currently in this “debate,” but these are my thoughts:
Team Number:
I would like to see six. It’s been that way in bionicle (and most lego themes honestly) for as long as anyone can remember. Plus, if your’re going to have six main bad guys (the rahkshi in this case) you’d want to have six adversaries for them.
Main Elements:
I’d like to see all the main elements again -fire (colors being red and orange), water (colors being shades of blue), ice (colors being white and trans light blue), air (Colors being shades of green), stone (colors being shades of brown/tan), and earth (colors being black and purple 'cause black with gray is boring, Orange was never really an earth element, and (even though purple isn’t either) it’s nice to introduce/keep new/rare colors now and then!) ).
The main controversy seems to be with air/jungle and stone/earth/sand so I’ll just explain that;
First of all, jungle’s not really an element; if you really want Lewa to control plants, then just make him a toa of plant-life! It makes a lot more sense then, for example, saying Tahu is the toa of Volcanoes!
Secondly, I understand the controversy between the three rock elments, but I feel that if the element of Earth was represented correctly it would make a lot more sense. Picture this: Toa of Earth can control the soil (so basically anything in the topsoil layer of the Earth itself). Toa of Stone could control rock, boulders, etc.
Other Elements:
In dealing with other elements, since we’re discussing this over your G3 pitch, I’d like to see them on the other islands from the main ones; It would give these matoran/toa more of a foreign feel.
I’d like to see lightning, iron, and plasma.
Lightning (colors being yellow and blue) makes sense as no other beings in your pitch, so far, has this power yet. Iron (colors being copper and silver (anything shiny)) also makes sense for the same reason, however I’d rather see the element dubbed Metal. Lastly, there’s plasma (colors being trans-orange and white). Some have pointed out that this is really similar to fire, which is a fair point. However, I feel that this element should be called Heat instead for a controversy regarding the element of fire:
In one of the Bionicle Adventures books, Vakama draws in all the heat from the room to the point where frost covers the area around him. Does this really make sense? It feels like he is more of a toa of ice! So, let’s instead take away the ability to draw or add heat from other toa/matoran and give it to the beings of the Heat tribe!
Light/Shadow:
I’m just going full opinion here. Both of these elements are awesome! Plus they add to the general archetype of good vs. evil in stories, which I feel is a must for any storyline.
Toa Kaita Equivalents
Edit: Just thought of a pretty cool idea. So remember the Toa Kaita? Well, I believe someone of these Message Boards suggested it already, what if we could do this again, but have them in pairs? Or, better yet, make them not limited to only merging with select elements/individuals?
For example, Gali merges with Onua to create a Toa who controls Mud (like how Gali controls mud in '08, but it actually makes sense)
Gali could also merge with Tahu to create a Toa who controls Steam/Water Vapor.
