20 thralls in a weekend ? No chance - maybe cannibals / exiles with fast leveling, but maybe cimmerians ?
I don’t know where you guys exp , I still use the reliable skeletons in UC in EL for leveling.
20 Cimmerians is more like a full time job for a week or more, and epically boring.
The fact that a few months back you could have a Dalinsia team within an hour of starting didn’t bother anyone much.
Personally, I’m all for it. Some not too cheap potion that gives maybe x3, x4 to level up. You just trade raw materials ( again, I’d like to emphasize it can’t be anything easily obtainable) for time.

But such debates are pointless anyway , FC either won’t do it or if he does it will be in the Bazaar for a hefty price
