I finally picked up this trinket up after scouring the AH for a week or so and want to make sure I get the most out of it. Is it generally best to use it on cooldown regardless of whether or not your other cooldowns or up or is it better to save it and match it up with a bloodbath? I'd imagine it's good to save it if you have an execute phase coming up, but how about for general usage? If anyone has done some testing the info would be appreciated, thanks.
