Yes, an individual Cane might be the toughest thing on two legs
I think for me this boils down the main concern that I had with the epilogue (please don't smite me or name the imbecilic monkey in your next book after me)
After 6 books of Tavi making decisions that I generally approved of, and ones that I openly cheered for in some scenes, the idea of the change to merit-based furycrafting (to me) was to make Aleran society more equal and fair, with less petty lordlings with the power to explode mountains. One of the reasons that Mr. Butcher gives for the development of the suffocating, non-innovative nature of Aleran society of Tavi's time was the desire to keep power by the Lords (see here -
http://www.jimbutcheronline.com/bb/index.php/topic,11756.600.html ). This decision certainly seems to rectify that, and seems to put Aleran society on a much better path forward.
However, when combined with giving the most powerful creatures (alone, without totems or furies) on the planet the abilty to use more power (Furies), is troublesome.
Granted, the explanation above about birth rates, and the differences in Canish society, might make the Canish less likely to horde power than Aleran lords - it still seemed different to how Tavi acted throughout the books - cautious, carfeul, and methodically well thought out....like when he tells Gaius that he is also taking the Canim back to their homeland to make sure that they keep their word.
Regardless of the mechanics of the world of Carna, which Mr. Butcher enlightens us on in the post above, the decision to give Furies to the Canim, even if it is based on his assessment / respect of their society, the current state of the world (semi-destroyed) seems very very hopeful (if not naive). It is hard to forget a character like Sarl, and not imagine what he could do with 600 years of furycrating, blood magic, etc...
I guess for me the issue is that this decision (giving Canim furycraft) seems to invite the same sort of stagnation, along with the possible power imbalances, that made the First Lord consolidating power that is described in the quoted post necessary in the first place...
I do want to be clear that I am most certainly not arguing with the author about the world he created, merely pointing out that one of the final decisions by a character that I followed for 6 books seems troublesome to me...Tavi would know about the reasons for the consolidaton of power for the "first" First Lord (if not, he experiences enough rotten super powerful High Lords to understand this intuitively), he talked about the stagnation of Aleran creativity and society, and, as is stated in Mr. Butcher's post about the Canim is that "they're essentially going to have to "become" more Aleran to get it". Thus, the upcoming changes to the Canim society would seem to make it even more likely that they would repeat the Aleran mistakes of the past that lead them to a dying civilization...I guess, for me, this would just be the one decision that Tavi makes throughout the books that I completely disagree with...and one that I personally see as making the Canim society as susceptible to having super powerful lords that can level mountains and run their society into the ground as the Alerans did pre-Vord...
That's it. Also, just to be clear. I think Alera and Dresden are my two favorite books series of all time...as is evidenced that this is the only message board that I have ever, ever posted on...
