Why Burial Chambers not Shaped one?

TRUE ANSWER:

Sustaining t3 is very easy with atlas strategies (removing all t3 except burial, and shaping the linked maps to burial chambers so they get higher tier and they can't drop from farming t3 map).

Less rerolling s*** mods, less rippy maps (yellow tier is harder).

Cheaper (white sextants, don't need chisel, posibly vaal all maps).

Easier, mobs have less hp and they die faster = more loot/h.

Drop rate of doctor is the same, so no real reason to do T8. Speed is all that matters. Rolling white maps is easier than rolling yellow maps as well. It's just faster all round.
