Where I do understand the reason players rush. It is highly annoying having to keep up when all you want to do is experience the full potential of a strike / raid. Having a matchmaking system that allows players to specify speed / long run would only maximise queue times. The best bet is finding like minded players on the forums.

I think it comes down to only having 6 strikes if there were more people wouldn't be as bored with them and would want to slow down and enjoy it more

Nah, the amount of strikes doesn't matter, look how many instances WoW has and the same thing applies. Yes they've been out for years, so it is more understandable for those who have played for a long time and are creating new characters, but many players only see loot, and not the story / details. Shame really but each to their own.
