I'm all for being efficient, but rushing ahead is FUCKING ANNOYING and just screams showoff to me. What the hell is the rush when you're leaving XP and glimmer on the table. You're not impressing anyone.
I don't really see how it's annoying to be honest. We've all done these strikes more times than we can count, and I don't feel like I'm missing out on anything by skipping past a few enemy encounters. And a minuscule amount of XP and glimmer from them isn't all that worthwhile.
