That is why I said that the setting would have served better as a return to Metru Nui. It natrually would have been overrun by the time they returned, so that is where you get the conflict.
In Legends of Metru Nui, when the toa were fighting Teridax, they were not at each others throats. They had to work through their anger for that, and in the end had enough unity to create a protodermis cage.
Personally though, I would have liked it if the metrutoran became the toa for '05. Akamou would have been a better traitor, as he basically was a traitor the entire run of Bionicle.
But still, out of the toa Metru...
What point? Please clairify. And if you are talking about the Hordika venom, that seems more like an excuse to me.
The hordika function was only moving the elbow. For a set function, that is rather underwelming.
I rather like the Rahtooka spinners also, but they were not the best functioning projectile weapons. I prefer the Midak Skyblaster, as you can fire it from any angle, and the ammo won't fall out.
The Visorak's function was the pincers. I find moving the pincer pieces a few millimeters to be underwhelming, like Keetongu's torso sliding foreword and the Hordika's elbows.
Then there's Keetongu's and Roodaka's weapons. They function rather well, but they are held loosly, and the parts flop around. Unfortunately, that is rather unavoidable.
