Determination vs spell speed and resetting stats at level 50 questions

[synesthetic]

spell speed also increases animation speed. might affect when instants land, since theres a delay on that.

I haven't seen anyone else say this. In contrast, I hear about plenty of people, including MNKs, complain about animation-locking, preventing them from using off-GCD instants sooner. So if you can give more detail or examples on why you say this, I know a lot of people who'd like to know as well.
