You can get 50 blood rubies from the PvP reward track, which only requires 30 mins of investment every day to do the PvP dailies. That's where I got half of mine. The other half from map completion. The only Bloodstone dailies I do are the 10 unstable magics and using the flight skills one.

I'm still using exotic armor for all of my characters, except for 2 pieces of ascended on my ele that I got from collection rewards. So, yeah...
