1st totally right you two.
2nd Either there would only be 3 seasons, so NO!
Or. the tree thing would have been hard to pull off and therefore that whole thread and Tyrek would have been wonky and season 5 seems to be largely based off of being the princess of friendship. So get rid of Pinkie Pride, All the Equestria games shows, and Twilight's Kindgdom, and I'm left with power ponies, and Daring Don't, which coincidentally are in my bottom tier of the shows. Two of which I don't feel like re-watching at all.
If you hated the shows with the key thread and Twilight Time, then you can push the Twilight becomes a princess off for the finale. As for me. I like where MMC took us too much to make it a finale.
On the other hand it might get rid of breezies, but, as they're a product, I doubt it.
