Feral as well. My druid was an alt who became my main, so I had a few gold and greater knowledge to 'do it right'. I didn't mess around with keeping greens updated every few levels, but rather invested in blues that actually lasted from low 30's all the way into my 50's, in 2 cases. if you're feral, i highly recommend the wolfwear harness, a level 31 blue w/ a ton af agi. It lasted me to the high 40's if I recall. Flintrock shoulders were great for me too. The quest reward pants from Gnomer will outclass greens into the 50's I believe, although there are some good blue options before then as well. My druid began life as a twink, so I had invested in the tigerstrike mantle- which almost gets you to outland without a green on your back. Since you use blues for so long, it's a good idea to strech them even further by researching the more reasonable enchants. You can get vision dust level enchants for a song, typically.
If you roll pvp server, it's a joy to stay well geared. I would frequently beat casters 5-6 levels over me (with 'the jump', of course), and rarely got beaten until outlands' resurgence of ganking.
