With MM being able to use pets again with Lone Wolf, I can imagine quickly summoning a pet would make life easier. Sometimes it will be smart to make use of the movement speed boost from cunning, damage reduction from tenacity, or heroism and leech from ferocity. But at the same time, who cares about pets as MM? I can't be bothered with the micromanaging the pet and dealing with that infamous AI.
So ideally that pet just disappears once it stops having a purpose, which gets annoying with the cast time of dismiss pet. 3 seconds to cast while standing still is so dreary. Imagine casting Dismiss Pet a 1000 times during this expansion, that's 50 minutes of your life wasted on something that could be instant cast.
So what are thoughts about making Dismiss Pet instant cast, while putting any Call Pet on a 3 second cooldown after casting the Dismiss?
