I mostly share these sentiments. I found the season incredibly boring and mostly awful. The lack of go-sees after the first or second episode, the lack of overseas travel, the weak concepts and even weaker styling on photoshoots, the numerous video challenges, the lack of range in types of shoots, these were all problems that bringing Tyra back won't necessarily fix. I use necessarily, because I'm hoping that since they had enough money to make Tyra happy, they increased the budget as well. Even so, Tyra, for all her faults, made a lower budget work in Cycles 1 & 2 to much better effect than the mess that was this season.
At its core, the industry is made up of more models who aren't "super" than are, and that's always been the case. I believe the show, if they took it as seriously as the Korean and Australian franchises do, can still achieve the ends of finding a well booked working model. In fact, I think this franchise is well positioned for living in an age of the insta-famous. They just need to find a girl who is unquestionably a model and push her after the season wraps.
I think a casting director or an agent from wherever the winner would sign with needs to be on the panel, that would help more than having Tyra back. But if they aren't serious about the modeling portion, then I at least welcome Tyra's entertaining antics.
