Not really, thanks to teleport. (Enigma for non-Sorc is generally a requirement to make it all the way IMO, but for Fishymancer even more so since it enables army positioning in the first place.)
I tested CS runs quite a bit at 97, but concluded it was worse XP than Baal or Nihlathak runs. With a godly shrine map it could be similar in terms of XP, but it's more dangerous, and the IG dies too often even with max GM... Overall I couldn't make it worthwhile, at least with the gear I had for Ric.
My goal is to be 100% Enigma-free with any/all of my entrants in this. Yes, that probably will add a good deal of time to each entry (if said entries manage to stay alive long enough to worry about it), but it's a personal preference for me.Loads of 99ers without teleport
