You have to realize people are running strikes for only a couple of reasons. Period. Marks, crypto engram (24), rep, bounty requirements. That's about it. So, if you get all of those things for completing the strike, and not killing every blip on the radar, then it makes sense to be efficient about doing it. It's about efficient use of your time. Honestly if you want to kill trash mobs don't play strikes on random matchmaking lists. Party up. Sure, you could kill everything in the cosmodrome on the way to Sepkis, but why bother? You could be dropping the laser grid in the first 30 seconds and working towards completion. Round trip Sepkis should be about 15 minutes. Any longer and you're doing it all wrong. Just saying. Final word: get the bad juju exotic bounty. One of the requirements is to complete 25 strikes. It's all about completion, thus efficiency, vice perfection. I can see your frustration. Just understand that this is waaaaay better than the turds that hangout at the start, never move, and let others complete the strike for them. Just saying. Pick your battles.
