I think Wizard101 needs an update of just bugfixes and optimization. Nothing else. Just fix bugs and optimize the game and its servers.
As much as I think the outrage train around the Spring and Summer updates is absolutely ridiculous, I have to admit they didn't add anything I ever asked for. I would much rather have an update solely dedicated to bugfixing than to clutter like playing as my pet.
KI is clearly worried about how newer players will view their game in 2020, seeing the texture/model updates. But I think new players would be much more worried about the models not even animating, the quest helper not pointing, battles randomly switching camera mode and then making you pass, discarding a card making the game freeze for seconds on end, someone fleeing freezing the game for a full turn, the game softlocking randomly when entering some areas, and more!
I put up with it a lot, since I'm a veteran player and so I'm willing to put up with a lot, but it seems like it's getting worse and worse, fast. Like, for example, when I was a kid I kind of accepted that the turn ended when the timer got to 2 or 3, not 0. But nowadays it's usually around 7 or 8! And I know it's not a problem on my end, I have an above average internet speed, and not to mention, I don't have this issue playing Pirate101.
