Am all for SGRs... if their inclusion feels natural and does not detract from any other game content (e.g. resources that might've been used fixing bugs are instead used to include SGRs).
The current approach seems great - integrating it into new content. So instead of 10 hetero fling options we might have 7 hetero, 2 gay and maybe 1 pansexual fling on Makeb.
But as it is SGR advocates are complaining about segregation. Makes one wonder if it'd have been better to leave out SGRs since either way you'll get complaints (and at least that way you do less work).
Oh well, we can wait for the next group to complain about discrimination/exclusion in/from SWTOR. Transsexuals? Asexuals? Polyamorists?
