Guessing this one will be changed further, 10 stacks in 10 seconds isn't a thing that'll happen outside of double missiles.
BotH got halved in duration, guessing they came to Pete's conclusion in the frost thread, and they're proccing too little. Halving duration means they likely doubled proc rate. Interesting changes.
Wush got changed to 1/sec for 10s as well. Looks like almost all trinkets at 20s duration were halved.
