I'm trying to get 100% on all the planets, and I've worked my way up to Alderaan. This set of achievements look like they will take forever though. Does anyone have any tips on where to find Strong Mobs of all the houses (Thul, Ulgo, Organa) and strong mobs for the Klilliks? I'm looking for heroic areas where a majority of the NPCs are strong, since a majority of the time for these achievement will be to find find the NPCs, not kill them. Heroic areas work best, but other areas with a high % strong mobs will work too.
I already found a heroic area to the north (some sort of dam, empire missions) that gives you plenty of gold Ulgos to kill, but now I need to find the silvers (strongs).
Thanks for any help,
