I only really use Taurog for nabbing Warmonger (Paladin or Warlord are better for nabbing specialist), and even then GG is better on many dungeons since Cleansing lets me easily beat physical resist bosses. If I could veto an altar, Taurog's would be it. Once in a blue moon I'll use him for resist stacking, but I pretty much would always prefer to see Dracul.
He certainly is easy to use and straightforward, though, and is notably quite powerful on dungeons with only a single boss. Just make sure you scout to ensure it's not a Goo Blob before you worship. I'm still waiting for a daily to have Taurog as an altar prep for something like a Berserker/Monk/Rogue/Tinker/Crusader, and have the boss turn out to be Wall of Goo. So many people are going to faceplant when it happens. And let's be clear, it's a matter of when, not if.
