This will never, ever happen but I figured this couldn't hurt.. It'd be nice to take a competitive Tyranid list that isn't just flyrant spam. Honestly, tell me the last time you saw any Nid players run a Trygon.
Proposed Changes:
Hormagaunts: Decrease cost to 4 pts/model. Make toxin sacs and adrenal glands the same prime. Allow them to purchase an upgrade for 1 pt/model called "Fertile".
Fertile: Most hormagaunts are already born pregnant and often lays their egg clutches immediately after being spawned. When the entire brood has been destroyed, an identical unit goes into ongoing reserves on a 2+.
Trygon: Gargantuan Monstrous Creature. Increase cost by +1 melta gun. Increase S/T to 7 from 6. Increase Bio-Electric Pulse to Assault 8. Must declare EITHER a Terror from the Deep (as per the Mawloc) OR creating a tunnel.
Serpentine Body: Allows the Trygon to perform two smash attacks instead of one but does not allow it to stomp.
Trygon Prime: GMC. Increase S/T to 7 from 6. Remove access to BioArtifacts. Increase
BS to 4. As per proposed Trygon rule, allow it to perform either a TFTD or create a tunnel. Give the Bio-Electric Pulse w/ Containment Spines a second profile which would be Assault 1, Large Blast, Haywire.
Serpentine Body: Allows the Trygon Prime to perform two smash attacks instead of one but does not allow it to stomp.
Subterranean Assault: Infantry units in reserves can deploy without rolling for reserves if a Trygon tunnel is available.
Tyrannofex: Remove the Rupture Cannon completely. That thing is awful. Instead, allow it to take a single BioCannon (same profile as the Hierodule's) for the same amount of points. Otherwise, keep the stats and other weapon options the same.
Deathleaper: Increase T to 5 and save to 4+. Decrease cost by 1 melta gun.
Tyranid Prime: Make him cost 100 pts/base. (Right now, a Hive Tyrant costs only 4 melta guns more..) Allow the option to upgrade him to a ML1 psyker for 20 points. Allow him to take Hive Commander and Old Adversary per the Hive Tyrant.
Allow him to take wings for +15 points and making his armor save +1 worse.
Genestealers: Decrease cost down to 1 melta gun/model.
Swarm Lord (c'mon, this guy costs almost as much as a

Wraith Knight): New Rule: Psychic Monstrosity. The
SL automatically knows all Tyranid psychic powers. New Rule: Monstrous Shadow in the Warp: All psykers within 24" of the Swarm Lord harness warp charges when casting with a +1 penalty (ie. a 4+ becomes a 5+). Additionally, they peril on any doubles. The
SL may also use warp charges during his psychic phase to try and negate a blessing/malediction on a 4+ with the number of successes needing to equal the number of charges required for the power.
Tail Biomorphs: Allow them to take advantage of the smash rule. Is a meltagun or 1.5 meltaguns for an extra
MC attack really that
OP?
Weapons/Biocannons: For
MCs with access to
TL Devourers, you never see any variation as everything else is so bad in comparison to 12 twin linked shots.
Venom Cannon: Change to AP3.
Heavy Venom Cannon: Increase Range to 48". Assault 2. AP3. Small blast.
Stranglethorn Cannon: Increase Range to 48". Assault 2. AP4. Ignore Cover.
Bioartifacts:
Norn Crown - Reduce cost by 1/2.
Reaper of Obliterax: Reduce cost by 1 meltagun.
