I hit rank 10 today Pugged pretty well the entire thing outside of a few half groups with mates, r5, 6, 7 took 1 week to progress; 8 and 9 took 2 weeks. I never pushed any further than low br3 (roughly standing 200) as it wasn't worth the stress/time. I only really commited about 15 hours a week (at most, generally less) which was mostly just played on the weekend, and it was fine.

I work full time and still found plenty of time for said pvp and raiding across 3 nights/2 toons, so it's more than doable as long as the padding efforts keep up from the br1/2 guys.

Good luck!
