Random maps sometimes not providing a one-jump asteroid to every player is a long standing bug, but they've never fixed that either. Just because something doesn't get an immediate hotfix doesn't mean it's not a bug.
Here's a post by Blair from the most recent patch notes:
re: a prior Q: Though this is a bit odd, but no changes to the Illuminator?
While we didn't touch LRM's directly, there is tons in there that changes relationships with them. We've tested the crap out of them and the status quo has changed.
Consider this example. Heavies were originally intended to be prototypical counter to LRM's. However, test after test said otherwise, despite our math. In one test sample that we ran over and over again, 102 Kodiaks vs 170 Illums (equal food comparison) the Illums actually beat the Kodiaks. When we updated the targetting and Kodiak ranges the Kodiaks defeated them handidly and were consistantly within error of the value we expected in our master balance spreadsheet. Obviously this isn't the only change as this is just one relationship but you get the idea - we dealt with them indirectly because we don't believe the fundamental problems are with LRMs (or Illums) themselves.
It seems to me as if their damage output has been taken into account with the game's overall balancing. If that's the case, and I have no reason to believe it's not, then they're now functioning as intended.
