How to survive(Shepard)without playing multiplayer?

I just wonder, do you guys hate the multiplayer that much? It takes like what? An hour to get to 100%? And every mp-character you promote adds to the new N7 spec ops team war asset that doesn't diminish over time. I thought it's just a gimick in the beginning but it turned out to be pretty entertaining, too. They did a really good job, on that front. With a rough start though.

Actually i can't achieve the low ems endings anymore while that war asset grands slightly over 8000(4000@50%)points by now. And i guess there are many guys with like 30000 or more points.
