Yeah, this is just insulting. 1:20 to challenge when you're supposed to have :30 WITHOUT stalling? Embarrasing.
Stuff like this happens in the business world all the time: while change can be a very healthy thing in any organization, too many suits decide to implement a series of small, annoying changes for no reason beyond keeping up the appearance of just doing something, anything. It's like Gov. Lepetomane in Blazing Saddles saying they had to "do SOMETHING to keep our phony baloney jobs!"
It reminds me of a baseball game since they instituted review there; people who slide into second or third base feet-first inevitably pop off the bag for a split second, but now teams challenge those slides by arguing that the millimeter they come off the bag is enough to warrant overturning a safe call if the second/third baseman held the tag. It delays games and completely goes against the entire idea behind umpiring and what replay was meant to accomplish in the first place.
