Getting back gnome faction from killing in SolA

[Algarana]

I'm very nearly in the same situation.

As others have indicated the Minos in the mino cave with Meladrath is amazing. I farmed it for about 2-4hrs and went from KOS to warmly for King Akanon and GemChoppers.

The quest shondo and the tonic, used 160p and purchased 16 stacks of Vastly Deep Ale, turned these in at a time, bit tedious but now I'm no longer KOS to the bankers and merchants will sell to me.

I've slaughtered kobolds for weeks doing groups at royals probably 5 different occasions for 2-3hr stints gaining Solusk Mining co rep. But I'm still KOS.
I've found 10 dwarfs in BB that give Miners 628 Faction, I've spent about 7hrs just grinding them out, but I'm still KOS.

So it's between the Miner reps, near as I can tell unless I am missing something. All this after a single session of about an hour killing gnomes. I would very much like an indicator of which faction I need to raise more as it's super annoying trying to guess which of the 4 factions listed the gnomes in Sol B are actually on Miners 628 or Solusek.
