I haven't played TE, but I've heard that it always gives you 3 stacks. And in SoD, the Miner might only get 1 stack. So, the nerfed Miner is more prevalent in SoD.

Let's do the math...

In TE, the Miner gets 3 stacks of 20-25 Troglodytes each, plus a second hero with 20-30 Troglodytes, plus you can buy 16 Troglodytes.

In total, on level 111, you get 96-121 Troglodytes, averaging 108 Troglodytes.

In SoD, the Miner gets from 1 to 3 stacks of 30-40 Troglodytes each, averaging 2 stacks. In total, you get an average of 121 Troglodytes.

So, even with the average values, you get more. Plus, there's the chance of getting 3 stacks and the chance of getting a native hero. Usually, heroic captures of strong creatures and Mermaids on level 1 are done precisely because of such scenarios; the number of Troglodytes on level 111 can reach up to 216. In TE, you can only achieve this by using Pandors to get Troglodytes...

Yes, there's a chance of getting only 1 stack, but usually, people restart if that happens. Therefore, on average, the SoD Miner is much stronger than the TE Miner. This is also evident in the reports - there aren't any particularly outstanding heroic captures for him in TE battles, and his castle's strength rating is somewhere in the middle in the Dungeon.
