Can we just take a moment to appreciate the fact that 2005 was the only year we got 14 canister sets instead of just 12? While we've gotten canister-sized sets on more than one occasion throughout the years, we never actually got bonus canister sets outside of the Toa Hagah, and that is super special when you think about it.
I read some complaints recently as to how the Toa Hagah are an "incomplete series" and were also clearly meant to be Toa Dume and Toa Nidhiki. The former statement is downright absurd for the aforementioned reason; did you expect that LEGO would produce 6 extra sets one year for no reason? No, that would've been at the expense at either the Toa Hordika or the Visorak and we would've gotten 2 sets less, not 4 more.
Also, while I somewhat enjoy the notion that Iruini could've been Nidhiki (because of his mask shape), if we're being completely honest, Norik would've been a lazy Dume. No change of mask type from Noble to Great? Lazy. Besides, Dume and Nidhiki were from two different "generations" of Toa and they'd have had to be marketed as having lived and worked separately. And they would've had to be given different tools from one another. Given the circumstances, they were handled well enough.
What I'm basically saying is that we got a treat and I for one loved it. Especially considering the pair wasn't available in Bulgaria and I had to seek them out abroad; it felt like a treasure hunt.
