Well, the tedium is that every now and then bad luck causes you to have to kill off a servitor and assuming it doesn't kill you, you're still stuck watching grass grow for another 40 hours before you can get another one.

I mean, its tedious. You can't go afk as a conjurer like you can as an assassin, because you might come back from a smoke break at the pit thanks to your demon getting pissy at you. Its just one of the realities of the class.

I still think its a very strong class though, all in all said, and I'd play it again if I had the energy to join a cabal.
