The entire profit taker missions (Repeller Systems drop included) need to be looked at. Its brutally unpleasant to require the constant re-running of a 2 minute mission to get a drop which is the only item locking a player out of ranking up. They (Repeller Systems) should be moved from level 5 Little Duck to level 2 so at least they can be purchased with standing.
I am so utterly jealous and sad that you have my repeller systems. :D
FWIW I'm up to 80 gyromag in 4 hours and not a single Rare drop.
