Why are witch doctor pets on such long timers to summon

Hey all,

I’m just messing about with Helltooth Gargs since the sets been buffed. I really can’t understand why Gargs are on a 60 second cd to summon them. If you are pushing and die more than once is basically gg go next. The only thing i can think remotely compares would be pushing with marauders and dying but even then you can summon some of your damage back. The issue isn’t that they die, it’s that you die and then can’t play the game for 1 min. I can’t see the logic for the skill having any CD honestly as it doesnt reset the cd of wrathful protector.
