Even in CB are black servants too strong?

[shovah]

I ask due to some recent tests, an un-experienced black servant with horror helm, lucky coin, chainmail of displacement and girdle of might (had him out by turn 15 on hard research) entered the deathmatch. Once there he managed to slaughter (without recieving any afflictions or, too my knowledge being hurt) a 250health, lucky, ethereal golden naga and a 150 health moloch with 28 attack. I know black servant thugs are powerful but isnt this a bit much? he now has the trident but i gave him a lycan amulet and now (due to his experience partly) he has a 22 strength, 21 attack, 27 defence (well 29 but im not counting his heroic quickness), 17 prot, he can fly, has quickness and a 2 atk per turn item, fear, ethereal and small regen. How much (if at all) do you think these things should be toned down?
