Thanks for catching the keyword! An older version was (obviously) called Tech-Priest Biologis, but I thought Genetor sounded better.
In terms of punchiness, it's directly comparable to the Enginseer, also at 45 points; 2 attacks at S5,
AP-2 (0.44 unsaved wounds on a marine), vs 4 attacks at S3,
AP-1 (0.33 unsaved wounds on a marine, but a bit better against
GEQ). It also lacks a laspistol, for all that matters.
Being an Elite rather than an
HQ choice might weigh against it, but the Datasmith is one too, and it weighs in at 45 for Enginseer stats with +1WS/
BS, a power fist, a better pistol, and a 2+/5+.
