It's not my fault you're unable to sprint past the small groups where it is unnecessary to fight. Some missions just don't require the wasted time battling through pointless enemies. Take Mercury for example, i can easily go from one end of map to the other running from doorway to doorway to spawn the next set of land to run on. Each section that spawns has it's own easy path to sprint through to the next doorway without attracting enough enemy attention to die. I personally only play 3 strikes per week to satisfy the requirements for the milestone. I'm not trying to spend 30 minutes killing every single enemy in the level when i can just run past certain groups. I also don't die too often since i am aware of which enemies you have to kill and which you can sprint past. I think you are more angry with the bad "mad dashers" that don't know the correct paths to take and the correct groups to try and pass. If you get hung up in the beginning and i make it to the end, you will spawn to my location saving you tons of unnecessary time. Heroic strikes are hard, but not too hard to pass certain enemies.
