Do I just have really bad luck or are other people experiencing really terrible drop rate on healer drops compared to other items..

example:

I have been doing coil for about 3 months now.. just turn 1 - 4 .. and for my coil job (healer) i have gotten waist and ring and lost a roll against 1 body, 1 head and 1 hands. thats 5 pieces in total i could have possibly had.. today i saw the ring again so lets say 6

Now about 8 weeks ago i started a new static with my FC, we trained 5 newbies up through the turns.. that means they had to get all of their gear. in those 8 weeks the DRG is in almost full allagan.. everyone has gotten multiple drops.. the tanks (who already had alot of gear cos they werent the newbies) got what they wanted and started passing.. I got FOUR drops for my tank on greed.. double the amount i have needed on healer and nearly as much as i have ever seen on healer.

So.. is it just my darned luck.. or is the RNG not playing nice?
