So I know this was talking about the whole being unable to queue ability thing (which threw me off at first when I logged in 1.19 for the first time, not even gonna lie) but since the whole animation thing was mentioned...

You can definitely still interrupt your animations if the skill has gone off. I can't tell you how many times I've used Pummel in the middle of Simian Thrash's animation. There's no way in hell I'd use it if I had to wait for 9 flashy hits to go off first.
