Endless Mode Wave 16 - Two quick balance/feedback suggestions

[Byzantium]

Really enjoying endless mode, two quick thoughts on Wave 16 after a few runs (best being 11.9m as Silent Sister)
1. Boss spawns appear to be in fixed positions all pretty close to 12 o'clock in the room, which makes it very easy to be in position to nearly insta-kill them on spawn: either spacing out where bosses of each type appear from around the room (if they have to spawn in a fixed position for technical reasons) or randomizing where they appear from (if they don't) would make them a much bigger part of the challenge during Wave 16.
2. Wave 16's map has for me so far always had a shrine on it, which could be just very good luck in 5 runs but I'm hoping means that there is just always one there, but I think it'd be better if there was never a shrine on Wave 16 to remove that one extra layer of blessing RNG from a given endless run.

Agreed with the boss spawn location. Also, the boss spawns eventually get so common that the names and health bars of the bosses start stacking on top of each other.
