All you say is true, the thing is that running (or hunting for them) is or can be very time consuming and that kills the otherwise good ISK/hour potential they do have, not to mention that it is also based on chance (luck). Taking all this into account is why I’m ranking it so low. I’d like to see you run a 5/10 DED with an Alpha accout, for the time being it is next to impossible. However with the changes coming to Alphas it certainly will be possible
