That really is a selfish attitude. For example I usually use a glimmer consumable when I'm running through Vanguard Roc. Killing all the little adds give me far more glimmer then racing to the boss and killing it for 50. Though I feel like I've been pretty lucky with vanguard strikes, since I usually don't seem to run into the AFK problems people have and haven't really run into people that wipe on purpose. If you look on the forums though you'd think those both would be huge huge problems.
