Still, msq is a faceroll content and gearing up is the only thing that helps you.
Get the ilevel 120/130 tomb gear and you should be fine with 1/2 of HW. Then equip every dungeon drop that's better then the gear to get through the 2nd half of the add on.

If you want to raid savage and even try the ultimate challenges, then you should consider to clear older savage content in synced mode. Because only then you really need the "skill" received by older synced down content.
