I did setup shaper's priority higher than elder's, but still it takes much more time than it actually should.
Though I don't know if my bot will be forced running map with memory fragment no matter its priority, so I did increase elder's priority slightly.
This way my elder influence may stop its growth and will be longer to reach up to t9's in order to get that t4 shaper's orb to upgrade relic chambers, restricting its drop in t3 burial chambers for best sustain.
