You must be new to This type of thing. Just like old school wow, in order to get to the dungeon you have to travel these dinstsndes through areas you have already explored. If I killed every level 6 dreg along the way I would never arrive with the respawning. Or the amount of time taken would not sufficiently match the quality of the reward. I've done every strike a million times. You need to step up your game or step down. If you can't keep up and insist on killing enemies that stand no chance against you, then go patrol a planet all day.
