No they have not, which is a bit of a shame as I want that gold bottle cap.
So far, I decided to use those festival missions to get tons of points for the plaza to change the fugly Rainbow Rocket castle. Good god, I remember why I despised the place compared to XY: Not counting the lack of voice chat, the fact you can't level up multiple levels at once is just a horrid design choice. I have 6K festival coins but since I have to keep getting 1-3 coins in order to have the leveling up catch up (usually to introduce random low level facilities with no purpose) it's going to be torment actually catching up to what things are worth. Plus the GTS one seems like it'll be successful anyway so there's even more to grind out. Why can't you just skip levels all at once and have the new buildings all presented to you in a row?
I also lost my drive to play through the battle tree, even though I have a team for normal mode and super. Ironically, it's not due to cheap difficulty or boredom from the early rounds (using Shiny Giratina Origin Forme and Shiny Mega Rayquaza in a double battle is tons of fun) but rather due to the godawful FPS drop, which on a N3DS without battle effect turned on became a huge problem in this mode moreso than in other situations. I can get why two god Pokemon would overwhelm the system with battle effects on, but you'd think they'd be capable of reducing the lag a little bit without any flashy battle effects taking place, so I stopped playing there. So far, only 37 hours spent with this game in total, only 10 of which have been after the post-game story, which is the least I've spent on any Pokemon game that launched after Gen II. Not a good sign for the lasting legacy of this game, honestly... I'm kinda wishing they did a lot more to expand this game and make it a proper third version with improvements to Gen VII as a whole (the deja vu of the story and the inability to skip those long, dull cutscenes killed the first 20 hours pre Aether for me) instead of a glorified content patch. The lack of a National Dex was the biggest killer by far and I still can't believe they would make the pokemon from the wormholes worthless as a result of it.
