If I am not mistaken the glint's challenge in central transfer chamber rewards dwarven points after clearing each wave (as well as I believe a bonus at the end). Seems like you could repeat that to keep farming.
If you go in a Prophercies outpost/town, turn on hard mode and have a look at some part of EotN map, you'll see the dungeon icons turn red like un-vanquished zones, so I guess HM and your tier 9 are coming soon
