How many more of these threads do we need to see?
The trend have not changed. Each legendary returns about every 3 months. Malak took 4 months.
At some point, you stopped farming for DR when you realise you can't get DR before / during the event. I can almost guarantee this because it's exactly what I did with RJT.
You must've either tried to gear up your Separatists for GTB / Padme or put in gears & energy for your arena / raid teams.
Take note, not everyone who have unlocked it will come here to gloat but many who can't will post here. So, that doesn't mean that majority can't unlock it.
Give it a month or two, you will definitely see many Malaks in arena / GAC, after they've had time to get him up.
