5 minute CD on SL engineering bombs?!

How in the heck do you justify giving SL ‘bombs’ a 5 minute CD?

I mean seriously how? You realize this almost make them pointless, right?
Engineering ‘bombs’ have always had a 1 minute CD.

Brother I have been playing on and off since WotLK missed dreanor and legion and bfa. And sometimes it’s just hit and miss. All I can say is rather large king was one of the best expansions I ever got to enjoy engineering on #biased #downwiththeLK
