True that, but the strange thing is that the piety generating potential of the cheaper glyphs manages to make him not a wasted altar for me very often. That's just a common misconception that gets repeated over and over - sure, he's probably the best thing to find (or prep) early, but I got rather easy CA's and Last Chances even when I swapped into him due to spamming cheap glyphs while munching popcorn. It's easy to tell it's possible because people seem to farm up an inordinate ammount of stat boosts all the time before taking either and then get both (and also start with petition), quite regularly. So what happens is that, yes, you get the really powerful stat boosts, but you also take the big refil stuff during the part of the game where you'd be if you just started in a piety farm and swapped over.
And at least you and I know that just one hit of each stat boost is plenty enough to get a big edge. Also, the ammount of shennanigans that happen with 100 piety swaps (from EM especially) into an effortless CA is quite silly, so anyone starting with EM (or Binlor or Mystera for that matter), doesn't mind finding him later at all.
The most notable thing is that the prepped wheytwut is so bloody strong that you can prep JJ al the time and still not feel inclined to really pull the levers and push the buttons to see all the sights. It's exactly the same thing as with old binlor - this guy removes the walls... and does some other stuff who cares? Other stuff - enormous damage boost and on demand full phys resists string o.O
