Trog thugs have a serious problem.

Taking out thugs often involves MR-resistable spells, like Paralyze, enslave, smite or even simple mind blasts. Trogs have poor MR. This wouldn't be too serious very early, but would be a huge liability later on.

Using trog thugs for fighting in a cold 2-3 environment may be better than Agarthans: even with reinvig from bless and item, Oracles/Lords may tire very quickly. An Oracle that can cast summon earthpower as well and might get away with it.
