Literally 90% of the strikes have objectives that don’t need all the enemies dead. Why would I bother doing that when I’ve already done the strike at least 100 times? There’s no replay ability in any of the strikes, they are boring as -blam!-, I don’t need to kill everything, the boss is the main objective, everything else you can do without killing enemies. For example - the Osiris strikes; running through an area that I don’t need to kill anything in and quickly get to the actual strike vs killing everything and adding up to 10 minutes onto the strike. I’m obviously going to choose the first option
