Once you're lvl 58 you're able to fly in outlands, so instead of grinding or doing some bs quest set your gatherbuddy on and let it do the magic I'm getting 1.2-1.3k per plant, It's a much more effective way of lvling instead of grinding and what not, once you're lvl 60 you can go back to kalimdor and do archeology to finish off lvling 
Happy Lvling your alts everybody!
