I hit BM 4-5 weeks ago, roughly. I have 1 BM commendation left for my full set. I am rank 71 on republic, I spend 30 minutes a day in Ilum. I work 40-50 hours a week and play a few hours each evening. It's very easy, just don't stare at your valor bar and play, if you enjoy it, it's not that much of a grind...
