Deathwatch makes frequent reference to killing Orkz but doesn't include a single word of information about them. Considering that DW uses the new "Horde" system, wouldn't you think it would be reasonable to include enough info on Orkz (and Eldar for that matter) to allow GMs to put together an Orc horde?
I took a look at the Ork Freeboota in RT but his stats seem more in line with the elite troops listed in DW and therefore don't make suitable horde stats. Same with the Eldar Corsair stats.
